This is a clean and simple Jekyll Theme built with the Bulma framework, providing a modern-looking site to start with.

The theme uses Alpine.js for its interactive components, such as mobile navbar and notifications.



This theme requires Jekyll 3.9 to be compatible with GitHub Pages.

Add this line to your Jekyll site's

gem "bulma-clean-theme"

And add this line to your Jekyll site's

theme: bulma-clean-theme

And then execute:

$ bundle

Or install it yourself as:

$ gem install bulma-clean-theme

hero_image: /path/to/image.jpg
setting in your page front matter, or in the defaults in your site's

You can also set the height of the hero by providing a Bulma hero height class in your front matter, such as

hero_height: is-fullwidth

in the page's front matter.

New in 0.7.1 - If you would like to darken the hero so the title stands out more, you can set

hero_darken: true
in the page's front matter. You can overwrite the default background colour by setting the
sass variable.

Table Of Contents

New in 0.5.8 - If you want to display a table of contents (toc) then add

toc: true
to your page's front matter. You can customise the default table of contents title by setting
toc_title: My Custom Title
in the page's front matter.

directory to store your posts as per normal Jekyll usage, with

paginate: 5
paginate_path: "/blog/page:num"

It can be in **Markdown format** if required.

Social Share Buttons

Share buttons will be displayed on your posts unless you hide them by adding

hide_share_buttons: true
to your config file.


For the top navigation, create a navigation.yml file in the

- name: Page 1
  link: /page-1/
- name: Blog
  link: /blog/
    - name: Page 2
      link: /page-2/

For the current page to have an active class, ensure the
