Icarus includes a new variant called Cyberpunk starting from version 3.0.0. The theme is inspired by the video game Cyberpunk 2077 developed by CD PROJEKT RED. This variant aims at providing a different Icarus experience to these who like dark-themed blogs. It should be noted that it uses recent web styling features that are not working correctly
in some legacy browsers, including Internet Explorer and legacy Microsoft Edge.

To enable the Cyberpunk theme, open _config.icarus.yml and make the following change:

1
2

- variant: default
+ variant: cyberpunk

You may also want to change the theme of highlighted code blocks. In that case, you can find some dark highlight.js themes here. Copy the file name, excluding the .css extension, and put it in the article.highlight.theme option in _config.icarus.yml. For example, if you want to change the theme to xt256, make the following change:

1
2
3
4
5

# Article related configurations

    highlight:
-         theme: atom-one-light
+         theme: xt256

Apart from the color palette, Icarus also used two image resources that are placed on the top navigation bar and bottom page footer from the official Cyberpunk 2077 website. If you wish to make further modifications to this theme variant, you can take a look at <icarus_directory>/source/css/cyberpunk.styl.
