Requirements

  • Hugo (version >= 0.109.0 extended), see this guide on how to install Hugo.
  • Git, see this guide on how to install Git.
  • Go (version >= 1.19), optional, required only when the Bilberry theme is used as a Hugo module; see this guide on how to install Go.

Quick Start

Site Initial Setup

  • Clone the Bilberry Hugo theme repository to your local computer:
git clone https://github.com/Lednerb/bilberry-hugo-theme.git

Alternatively, you can download it as a ZIP file and extract into the bilberry-hugo-theme directory.

  • Create a new site:
hugo new site my-new-blog
  • Delete the default archetype:
rm my-new-blog/archetypes/default.md
  • Copy the example site content, including the config.toml file:
cp -r bilberry-hugo-theme/v4/exampleSite/* my-new-blog

Theme Installation Options

Use this option if you want to pull in the theme files as a Hugo module from the main Bilberry Hugo theme repository. This option makes it easy to keep the theme up to date in your site.

  • Initialize your website as a Hugo module from the site’s root:
cd my-new-blog
hugo mod init github.com/<your-user>/my-new-blog

Following the Hugo module initialization, you may have the following warning: module " github.com/Lednerb/bilberry-hugo-theme/v4" not found, which should be ignored.

  • Pull theme files to add new content to your website:
hugo mod vendor

If you need more details on how to use Hugo modules, please read the Hugo documentation .

Option 2: Adding the Theme as a Git submodule

Use this option if you want to pull in the theme files as a Git submodule from the main Bilberry Hugo theme repository. This option also makes it easy to keep the theme up to date in your site.

  • In the my-new-blog/config.toml file, uncomment the theme property for Options 2 and 3, and comment out the theme property for Option 1:
# Option 1 (recommended): adding the theme as a hugo module
# theme = "github.com/Lednerb/bilberry-hugo-theme/v4"

# Options 2 and 3: cloning/copying the theme files
theme = "bilberry-hugo-theme/v4"
  • Add the Bilberry Hugo theme as a Git submodule from the site’s root:
$ git submodule add https://github.com/Lednerb/bilberry-hugo-theme.git themes/bilberry-hugo-theme

Option 3: Copying the Theme Files

Use this option if you want to customize and maintain your own copy of the theme directly.

  • In the my-new-blog/config.toml file, uncomment the theme property for Options 2 and 3, and comment out the theme property for Option 1:
# Option 1 (recommended): adding the theme as a hugo module
# theme = "github.com/Lednerb/bilberry-hugo-theme/v4"

# Options 2 and 3: cloning/copying the theme files
theme = "bilberry-hugo-theme/v4"
  • Copy cloned (or unzipped) theme files in the previous step to the my-new-blog/themes directory:
cp -r bilberry-hugo-theme my-new-blog/themes/bilberry-hugo-theme

Important: Do NOT change the name of the themes/bilberry-hugo-theme folder in your site’s root. Renaming this folder will break your site.

Configuration

To customize your website according to your needs, edit the config.toml file in the site’s root directory by adjusting the settings. All parameters that need to be configured are commented out or disabled.

The Algolia Search is enabled in the config.toml file that comes with the example site; therefore, if you don’t plan to use it, disable it by setting the algolia_search property to false.

Webserver

  • To build and serve the site, execute the following command from the site’s root:
cd my-new-blog
hugo server

Free Hosting

To deploy and host your website for free, you can use either GitHub Pages or Netlify .

Important: When hosting on GitHub Pages, you should add an empty file named .nojekyll to the site’s root to avoid the issue with Font Awesome’s icons not being loaded.

Features

Default Post Types

Bilberry theme comes with a set of predefined post types, namely article, audio, code, gallery, link, page , quote, status, and video, where the article type is the default.

To create a new content, use the hugo new command. Content can be created in two ways: a single page or a page bundle .

Single Page

To create new content as a single page, you can use the following command:

hugo new <content-type>/my-single-page-content.md

Page Bundle

Or, new page bundle content can be created as follows:

hugo new <content-type>/my-page-bundle-content/index.md

For example, you can create a new article as a single page and a new gallery as a page bundle using the following commands respectively:

hugo new article/my-single-page-article.md
hugo new gallery/my-page-bundle-gallery/index.md

The page post type is the only one that can be used in the top navigation bar. Pages can be ordered using the weight front matter variable, which should be set to a non-zero value. A page with a lower weight will be displayed first.

The page content can be a static page, such as an About page, or a link to another page, internal or external.

The link post type always links to an external site and can be used with or without a background image.

Top Navigation Bar

If you want to permanently display the top navigation bar with the search text field and page items, set the permanentTopNav parameter to true in the config.toml file.

If you want to display the top navigation bar when scrolling down the page, set the stickyNav parameter to true. But this will only work when the permanentTopNav is also set to true.

Please note that the top navigation bar is minimized by default on mobile devices.

Light/Dark Theme Mode

Switching between light and dark theme mode can be enabled by setting the enableLightDarkTheme parameter to true:

[params]
  enableLightDarkTheme = true

Bilberry theme includes built-in content search via Algolia SAAS . You can see this in action on the demo site by clicking on “hamburger” and typing something in the search text field, such as “support.”

Initial Setup

To enable and configure search functionality for your site, follow these steps:

  1. Register for a free Algolia Search account at https://www.algolia.com/ .
  2. Add a New Application. You can choose the COMMUNITY plan.
  3. Switch over to Indices and create a new index.
  4. Switch over to API Keys and copy your Application ID, Search-Only API Key, and chosen Index name to your config.toml file.
  5. Make sure that the algolia_search parameter is set to true.
  6. Follow the instructions in the section Update Algolia Index and proceed to the next step.
  7. To complete the initial setup, go to the tab Configuration of your newly created indices, select the Facets in the section FILTERING AND FACETING, and add the language attribute with the filter only modifier in the Attributes for faceting option. If, after adding the language attribute, the Unknown attribute error is shown, ignore it.

Update Algolia Index

You have to repeat this step every time you change a post or publish a new one to update the search index.

Execute the hugo command in the site’s root directory to generate the index.json file.

Manual Upload
  1. Head over to the public/index.json file and copy its content.
  2. Log in to your Algolia account, open your index, and click on Add records manually.
  3. Paste the copied text from the index.json file.
  4. Verify in the Browse tab of your index that the index records were uploaded correctly.
  5. In case you have a multi-language setup, make sure that you repeat the steps above for all public/{LANG}/index.json files.
Automated Upload
  1. Switch to the algolia directory and install the required dependencies by executing the following command:
cd algolia
npm install
  1. Run the data-upload.js from the algolia directory as follows:
npm run data-upload -- -f ../public/index.json -a <algolia-app-id> -k <algolia-admin-api-key> -n <algolia-index-name>
  1. The algolia-admin-api-key argument, namely your Algolia account’s Admin API Key, is used to create, update, and delete indices, and it should be kept secret.
  2. Add the -c or --clear-index option if you want to clear the corresponding Algolia index before starting a new upload.
  3. Log in to your Algolia account and verify in the Browse tab of your index that the index records were uploaded correctly.
  4. In case you have a multi-language setup, make sure that you repeat the steps above for all public/{LANG}/index.json files.

Also, you can read this write-up on how to automate data upload to Algolia index if you host your Bilberry theme-based website on Netlify, or this write-up using GitHub Actions.

Keyboard Shortcuts

Type s to open the navigation bar and set the focus to the search input field. To remove focus, press the Esc key.

Reposted Article/Duplicated Content

If you need to repost an article from another website or duplicate content on your site, you should link it to the original URL so it’s correctly processed by SEO. To do so, define the original_url front matter variable in your post, for example:

original_url: "https://example.org/path/to/content"

Estimated Reading Time

To show an article’s estimated reading time, set the showReadingTime parameter to true in the config.toml file. You can override the estimated reading time by setting the article’s readingTime front matter variable to a value you want. If you set this variable to 0, the reading time will not be shown.

readingTime: 7 # will show "7 MIN READ"
readingTime: 0 # reading time will not be shown

Summary Splits

There are three options for how Hugo can generate summaries of content which will be used as a short version in the summary views, such as a home page and tags or categories pages.

Automatic Summary Split

Using the first 70 words of your content, Hugo automatically generates the summary followed by the Continue reading link.

Manual Summary Split

Add the `

` summary divider to your content. Any content before the divider will be used by Hugo as a summary of that content. The generated summary will also be followed by the Continue reading link.

Front Matter Summary Split

To define a summary that differs from the text that starts your article, use the summary front matter variable, for example, summary: "Here goes my summary". This summary will also be followed by the Continue reading link.

No Summary Split

If you want to display the entire article without the Continue Reading link, set the noSummary variable to true in your content file.

Open Graph Metadata

The following base Open Graph metadata is included by default in all pages: og:site_name, og:title, og:description, og:type, og:url, article:section, article:published_time, and article:modified_time where the article:published_time tag will have the same timestamp value as the date front matter variable.

Additional metadata can be included by adding the following front matter variables:

  • publishDate for article:published_time
  • images for og:image
  • audio for og:audio
  • videos for og:video
  • series for og:see_also

For example:

title: "Open Graph Metadata with Extra Front Matter Variables"
date: 2022-12-19T19:00:00-05:00
publishDate: 2022-12-19T20:00:00-05:00
lastmod: 2022-12-19T21:00:00-05:00
images: ["/img/content/article/open-graph-metadata-with-extra-front-matter-variables/thumbnail.jpg"]
audio: "/audio/icq-remix.mp3"
videos: ["/video/test_mp4_video.mp4"]
series: ["My Cool Series"]

Table of Contents (TOC)

To enable the automatic creation of a table of contents (TOC), set the toc front matter variable to true in your article. If the article’s markdown contains appropriate headings, Hugo will generate a table of contents at the beginning of the article.

By default, a TOC is generated if the content’s word count is greater than 400. The tocMinWordCount parameter defines this value in the config.toml configuration file.

The headings that are taken into account for a TOC are from H2 (##) to H5 (#####) inclusive. Also, if you want to display a TOC at a specific point in your article, set the toc front matter variable to false, and use the toc shortcode like this:

{{< toc >}}

Series Taxonomy

In case you want to group some articles as a series, you have to add the series front matter variable to each article and set its value to the name of the series, for example, series: ["My New Super Series"].

The page at <site-base-url>/series/ will list all the series. To list all articles for a particular series within markdown, you can use the series shortcode with the series name in question, for instance:

{{< series "My New Super Series" >}}

Images

External Images

If you would like to use external images, such as those stored on another server or in the cloud, as a featured image for your article or in the gallery post type, you can use them by setting the appropriate front matter variables with the absolute URL values:

# /content/article/my-external-featured-image-post.md

featuredImage: "https://example.org/images/my-image.jpg"

# /content/gallery/my-external-gallery-post.md

gallery: [
"https://example.org/images/gallery-image1.jpg",
"https://example.org/images/gallery-image2.jpg",
"https://example.org/images/gallery-image3.jpg"
]

Image Modal Zoom

When you include an image larger than the content area, the image becomes interactive, and a larger version can be opened in a lightbox. Modal zoom will work only for images that are added using the standard markdown annotation, e.g., ![Image alt text](/my_image.png) or ![Image alt text](/my_image.png "Image figure caption") for images with a figure caption. Please note that this feature will not work for images added using raw HTML.

There are two options for adding a featured image to a post. The first approach is to use a single-page post with the featuredImage front matter variable, where the value for this variable should be either the path relative to the base URL or an absolute URL.

Alternatively, when using a page-bundle post, the intended featured image should be named featuredImage.* where the * is the image file extension, e.g., jpg, png, etc. Also, it should be placed within the page bundle in question, for example:

content
└── article
    └── my-post-with-featured-image
        ├── featuredImage.png
        └── index.md

Automatic Image Resizing

Bilberry theme includes built-in automatic cropping and resizing only for featured and gallery images, activated by default. However, if you want to disable it, set the resizeImages parameter to false in the config.toml file. Also, this feature can be disabled at the post level by setting the resizeImages front matter variable to false.

For a featured image to be cropped and resized, it should be named featuredImage.* and placed within the page bundle’s folder.

NOTE: a featured image defined via the featuredImage front matter parameter will NOT be cropped and resized.

If you want to display an image as a hyperlink, use the hyperlink-image shortcode as follows:

{{< hyperlink-image "<image-text>" "<image-url>" "<link-url>" >}}

Video

The following video hosting providers are supported: YouTube , Vimeo , Prezi , Bilibili , and PeerTube . Videos in the MP4 format, either stored externally or within the site’s static folder, are also supported. There are two options to display video embeds.

The first option is to use a post of the video type. Use the following command to create your video post:

hugo new video/<post-name>.md

Then set the appropriate front matter variable while removing the others:

youtube: "<youtube-video-id>"            # https://www.youtube.com/watch?v=M7IjJiZUutk -> "M7IjJiZUutk"
vimeo: "<vimeo-video-id>"                # https://vimeo.com/239830182 -> "239830182"
prezi: "<prezi-video-id>"                # https://prezi.com/v/5z9shnq7jzxs/what-to-study/ -> "5z9shnq7jzxs"
bilibili: "<bilibili-video-id>"          # https://www.bilibili.com/video/BV1Sx411T7QQ -> "BV1Sx411T7QQ"
peertube: "<peertube-video-id>"          # https://vids.tekdmn.me/w/w7WGHX7Lb6mCrbrpF3Xb8V (entire URL)
mp4video: "<video-file-url>"             # location of video file (only mp4)
mp4videoImage: "<image-video-file-url>"  # location of poster image

For example, if an MP4 video and its image are stored in the static folder, you can set the corresponding front matter variables as follows:

mp4video: "/<video-file-name>.mp4"
mp4videoImage: "/<image-video-file-name>.png"

The second option is to use the video shortcode within markdown content in a post of the article type as follows:

<!-- YouTube -->
{{< video type="youtube" id="<youtube-video-id>" >}}

<!-- Vimeo -->
{{< video type="vimeo" id="<vimeo-video-id>" >}}

<!-- Prezi -->
{{< video type="prezi" id="<prezi-video-id>" >}}

<!-- bilibili -->
{{< video type="bilibili" id="<bilibili-video-id>" >}}

<!-- PeerTube -->
{{< video type="peertube" id="<peertube-video-id>" >}}

<!-- MP4 external -->
{{< video type="mp4" url="<video-file-url>" imageUrl="<image-video-file-url>" >}}

<!-- MP4 in site's static folder -->
{{< video type="mp4" url="/<video-file-name>.mp4" imageUrl="/<image-video-file-name>.png" >}}

PeerTube Configuration

Because there is no one PeerTube site, you need to indicate which ones your videos use, meaning you can’t use just the video ID. Instead, copy in the entire watch URL, and it’ll be transformed into the correct embed URL to use.

There is an instance finder if you want to start hosting your videos on PeerTube but don’t know which instance to join.

Audio

The following audio streaming providers are supported: Mixcloud , SoundCloud , Spotify , and TuneIn . Audio files in the Ogg, MP3, or WAV formats, either stored externally or within the site’s static folder, are also supported. There are two options to display audio embeds.

The first option is to use a post of the audio type. Use the following command to create your audio post:

hugo new audio/<post-name>.md

Then set the appropriate front matter variable while removing the others:

spotify: "<spotify-track-id>"        # https://open.spotify.com/track/3W2lz1sg6m4sEzjmoTjmdE?si=0659fd12179840dd -->
3W2lz1sg6m4sEzjmoTjmdE
soundcloud: "<soundcloud-track-url>" # https://soundcloud.com/lightbooks/alchemist-08-new-world-order-snip
tunein: "<tunein-track-id>"          # https://tunein.com/embed/player/t117894382/" --> t117894382
mixcloud: "<mixcloud-track-id>"      # https://www.mixcloud.com/scienceforthepeople/445-ai-ant-intelligence/ -->
scienceforthepeople/445-ai-ant-intelligence
audiofile: "<audio-file-url>"        # location of audio file (only ogg, mp3, or wav formats)

For example, if an MP3 audio file is stored in the static folder, you can set the audiofile front matter variable as follows:

audiofile: "/<audio-file-name>.mp3"

The second option is to use the audio shortcode within markdown content in a post of the article type as follows:

<!-- Mixcloud -->
{{< audio type="mixcloud" id="<mixcloud-track-id>" >}}

<!-- SoundCloud -->
{{< audio type="soundcloud" id="<soundcloud-track-url>" >}}

<!-- Spotify -->
{{< audio type="spotify" id="<spotify-track-id>" >}}

<!-- TuneIn -->
{{< audio type="tunein" id="<tunein-track-id>" >}}

<!-- MP3 external -->
{{< audio type="audiofile" url="<audio-file-url>" >}}

<!-- MP3 in site's static folder -->
{{< audio type="audiofile" url="/<audio-file-name>.mp3" >}}

Google Analytics

Bilberry theme comes with built-in support for both v3 and v4 of Google Analytics . You should set the value of the googleAnalytics property in the config.toml file to enable it.

Such value for Universal Analytics v3 is prefixed with the UA letters. So, suppose you migrate your existing website to the Bilberry theme, and your website is already tracked in Universal Analytics, given that the corresponding property was created before October 14, 2020. In that case, you should continue using the v3 value in the config.toml file. However given that Universal Analytics will no longer process new data in standard properties beginning July 1, 2023, you will have to create a Google Analytics v4 property linked to your v3 property.

If you created your property after October 14, 2020, you’re likely using a Google Analytics v4 property already, and the value for such property is prefixed with the G letter. In that case, you should use the v4 value in the config.toml file.

Comments

To allow readers to comment under your articles, you can use either Commento , Disqus , Giscus , or Utterances .

Note to developers/contributors: if you want to submit a new commenting engine for integration with the Bilberry theme, it must meet the following criteria:

  1. The engine should be offered as a SAAS, i.e., you only need to create an account and configure the necessary settings on the engine’s website.
  2. If the engine is offered as a SAAS, it must have a free tier plan.
  3. All the configuration steps needed to integrate a third-party commenting service must occur only in the config.toml file and not within additional configuration in the partial files or any other.

Commento

Follow this guide if you want to use Commento Cloud Service which is not free of cost.

In case you want to use Self-hosting Commento, follow these instructions .

Then uncomment the commentoJsURL parameter in the config.toml file:

#[...]
[params]
  #[...]

  # Commento
  commentoJsURL = "http://localhost:8080/js/commento.js"

Disqus

To allow readers to leave comments under your articles, sign up for free on Disqus website. Then create a new site and set the disqusShortname parameter to your site’s short name in the config.toml file:

#[...]
[params]
  #[...]

  # Disqus
  disqusShortname = "lednerb"

You can manage and moderate the comments either on your website or using the Disqus management panel.

Giscus

Follow instructions on Giscus website. Once you complete the prerequisites for your GitHub repository and select a discussion category, values for giscusRepositoryId and giscusCategoryId will be automatically generated. Then, in the config.toml file, set the giscus parameter to true and the properties mentioned above, respectively:

#[...]
[params]
  #[...]

  # Giscus
  giscus = true
  giscusJsUrl = "https://giscus.app/client.js"
  giscusRepository = "Lednerb/bilberry-hugo-theme"
  giscusRepositoryId = "R_kgDOGX153A" # generated by Giscus website
  giscusMapping = "pathname"
  giscusCategory = "General"
  giscusCategoryId = "DIC_kwDOGX153M4B_2Vz" # generated by Giscus website
  giscusTheme = "light"
  giscusDarkTheme = "dark"
  giscusReactions = "1"
  giscusEmitMetadata = "0"
  giscusLanguage = "en"
  giscusCrossOrigin = "anonymous"

Utterances

Follow instructions on Utterances website. Once you complete the prerequisites for your GitHub repository, set the utterances parameter to true in the config.toml file:

#[...]
[params]
  #[...]

  # Utterances
  utterances = true
  utterancesJsUrl = "https://utteranc.es/client.js"
  utterancesRepository = "Lednerb/bilberry-hugo-theme"
  utterancesIssueTerm = "pathname"
  utterancesLabel = "Comment"
  utterancesTheme = "github-light"
  utterancesCrossOrigin = "anonymous"

Archive Page

The archive page will be available at <site-base-url>/archive/ as soon as you copy the themes/bilberry-hugo-theme/exampleSite/content/archive.md file to the content directory of your site. By default, the published content is grouped by year. To group the content by year and month, set the archiveDateGrouping parameter to the 2006-01 value.

To display the archive link in the footer, set the showArchive parameter to true.

To add the archive link to the top navigation bar, create a new page with the following command:

hugo new page/archive.md

Then, in the newly created content/page/archive.md file, set the link front matter variable to the /archive/ value and completely remove the target variable.

Responsive Design

Bilberry theme is optimized to look good on all devices, namely desktops, tablets, and smartphones.

MathJAX Markup

To enable the MathJAX markup support, set the enable_mathjax parameter to true in the config.toml file.

Disabled JavaScript Support

Although this theme has a lot of features that only work with enabled JavaScript, it also fully supports disabled JavaScript. Disabled Javascript will not break any styling or essential functionalities of your website.

You can test the behavior of the demo site by disabling JavaScript in your browser.

Trimmed JavaScript Size

By default, this theme’s JavaScript bundle contains the Moment.js library, which is large enough, though they add real value.

Therefore, to reduce the size of the downloaded JavaScript bundle, you can choose whether using the Moment.js library remains enabled (currently the default) via the enableMomentJs configuration parameter. Setting it to false would reduce the bundle size by ~262 kB gzipped.

Raw HTML

If you want to include raw HTML in your markdown content, set the unsafe setting in the config.toml file to true:

[markup.goldmark]
  [markup.goldmark.renderer]
    unsafe = true

Customizations

Hooks

If you need to integrate your website with a third-party service or to customize it further, you can use the following hook partials: hooks/head-end.html , hooks/body-start.html , and hooks/body-end.html . Copy the file in question into your site root’s layouts/partials/hooks folder and add the necessary code, for example, as in this hooks/body-end.html file that contains integration with Umami web analytics.

<script async defer src="https://analytics.umami.is/script.js"
        data-website-id="29b02d61-3df1-433f-8bb7-cba0ec70c9f7"></script>

Favicons

To add favicons, proceed with the following steps:

  1. Visit https://realfavicongenerator.net/ website, and generate favicons according to your needs.
  2. Copy and paste the generated files into your site’s /static folder.
  3. Edit the /layouts/partials/favicon.html file, then copy and paste the HTML code from the generated instruction.

Important: You have to follow the Quick Start instructions or manually copy the /layouts/partials/favicon.html file from the theme to your site’s /layouts directory.

Also, check out this tutorial on how to add favicons to Bilberry theme-based website.

404 Page

To customize your 404 page, copy the themes/bilberry-hugo-theme/layouts/404.html file to your site’s layouts/404.html and edit the file according to your needs, for example, change the message, icon class etc.

Custom Post Types

With the Bilberry theme, you can create new post types easily. For example, suppose you want to create a new type named book. Then you should do the following:

  1. Copy the default themes/bilberry-hugo-theme/layouts/partials/content-type/article.html to your site’s layouts/partials/content-type/ folder.
  2. Rename the file to your custom post type, namely book.html.
  3. Customize the newly created file, for instance, change the icon in the bubble to fa-book that is available on Font Awesome Icon website:
<i class="fas fa-fw fa-book"></i>
  1. To create new posts, use the book post type prefix:
hugo new book/my-favorite-book.md`

If you want to use custom front matter variables, create a book.md archetype in your site’s archetypes/ directory.

Individual Posts

You can customize your posts as follows:

  1. To exclude posts from your blog’s index but still show up in categories, add excludeFromIndex: true to your post’s front matter.

  2. To pin one or more posts to the top of the index page, uncomment the pinnedPost parameter in the config.toml file. Then set its value to the post’s relative URL, for example, /article/installing-bilberry-theme/. When pinning multiple posts, the relative URL values should be separated by a comma. The pinOnlyToFirstPage parameter allows you to choose whether to display pinned posts on the index page only or on all pages.

  3. A custom icon can be declared per post, by specifying a font-awesome icon in the post’s front matter, such as icon: fa-thumb-tack for a pinned post.

  4. If you want to change the default post types(e.g., replace the pencil icon for the article post type another one) copy the original content type file to your site’s layouts/partials/content-type/ directory and edit it there. Otherwise, your changes will be overwritten when you update the theme to the latest version.

Syntax Highlighting

Syntax highlighting for code blocks in your posts is implemented using Hugo’s built-in Chrome code highlighter. Highlighting for code blocks in your posts can be customized at the site level or per code block.

To change the default configuration at the site level, adjust the properties in the [markup.highlight] section of the config.toml file. For example, you can change the default monokai style to the one from the Chroma Style Gallery .

Per the code block, the following parameters can be personalized: linenos, hl_lines, linenostart, anchorlinenos, lineanchors, and hl_inline, for example:

```java {linenos=inline, hl_lines=“7-12 21-26”}

// … code

```

Read Hugo’s documentation for more details.

Layout, Colors and Fonts

Site layout and styling are implemented using SCSS along with npm , which is only used for dependency management. Layout, colors and fonts can be customized via variables defined in the assets/sass/theme.scss file.

For example, if you want to customize the $base-color variable, you should define the baseColor parameter in your site’s config.toml file.

$base-color: {{ .Param "baseColor" | default "#1d1f38" }};

[params]
  baseColor = "#ff8080"

CSS and JS modules

This theme supports hot-swappable CSS and JavaScript extensions, which can be specified using the css_modules and js_modules list parameters in your site’s config.toml file. Modules can be specified either relative to the static directory (e.g., exampleSite/static/custom.css) or as a URL:

[params]
  css_modules = ["custom.css","//cdnjs.cloudflare.com/ajax/libs/cookieconsent2/3.1.0/cookieconsent.min.css"]

Modules are imported in the order they appear in the list and processed immediately after the default Bilberry CSS and JS files.

You can use the cookie consent solution to add cookie consent information by loading the needed resources as external CSS and JS modules.

Use the configurator on the cookie consent website to generate the required initialization code and add it to a local static/init-cookieconsent.js file, for example:

// https://cookieconsent.insites.com/download/#
window.addEventListener('load', function () {
  window.cookieconsent.initialise({
    'palette': {
      'popup': {
        'background': '#cc0033'
      },
      'button': {
        'background': '#fff'
      }
    }
  })
})

Then you only need to modify the config.toml file to load the local init script and the libraries. You can either download the files and put them in your site’s /static directory or reference them directly using a CDN. Storing these files on your website reduces external dependencies, increases privacy, and allows you to develop your website in an offline environment.

css_modules = ["//cdnjs.cloudflare.com/ajax/libs/cookieconsent2/3.1.0/cookieconsent.min.css"]
js_modules = ["//cdnjs.cloudflare.com/ajax/libs/cookieconsent2/3.1.0/cookieconsent.min.js","init-cookieconsent.js"]
