Doxygen Awesome is a custom CSS theme for Doxygen HTML-documentation with lots of customization parameters.


I really like how the Doxygen HTML-documentation is structured! But IMHO it looks a bit outdated.

This theme is an attempt to update the visuals of Doxygen without changing its overall layout too much.


  • 🌈 Clean, modern design
  • 🚀 Heavily customizable by adjusting CSS-variables
  • 🧩 No changes to the HTML structure of Doxygen required
  • 📱 Improved mobile usability
  • 🌘 Dark mode support!
  • 🥇 Works best with doxygen 1.9.1 - 1.9.4

All theme files are located in the root of this repository and start with the prefix doxygen-awesome-. You may not need all of them. Follow the install instructions to figure out what files are required for your setup.

Choosing a layout

There is two layout options. Choose one of them and configure Doxygen accordingly:

Available theme variants

Base Theme (1)

Comes with the typical Doxygen titlebar. Optionally the treeview in the sidebar can be enabled.

Required files: doxygen-awesome.css

Required Doxyfile configuration:

GENERATE_TREEVIEW = YES # optional. Also works without treeview
HTML_EXTRA_STYLESHEET = doxygen-awesome-css/doxygen-awesome.css

Sidebar-Only Theme (2)

Hides the top titlebar to give more space to the content. The treeview must be enabled in order for this theme to work.

Required files: doxygen-awesome.css, doxygen-awesome-sidebar-only.css

Required Doxyfile configuration:

HTML_EXTRA_STYLESHEET = doxygen-awesome-css/doxygen-awesome.css \

Caution: This theme is not compatible with the FULL_SIDEBAR = YES option provided by Doxygen!

  • This theme was initially inspired by the vuepress static site generator default theme.
