About

The "mdBook Auto Theme" browser extension allows you to easily switch between different themes on websites that were generated by mdBook. With this extension, you can select your preferred themes for both light and dark mode, and it will automatically apply your selected themes on any website generated with mdBook. 

An important feature of this extension is that you can define your selected themes globally, so you don't have to manually select the theme on every new page you load. Note that changing the theme requires a page refresh.

You can try the extension on the website of mdBook itself, which is generated with mdBook, for example, see https://rust-lang.github.io/mdBook/.

The current themes available in mdbook and therefore by this extension are "Light", "Rust", "Coal", "Navy" and "Ayu".

You can reach the settings menu by clicking on the icon in the right top of your browser, you may need to open some extension menu.
