There are a few ways you can make style changes to Congo.
Colour schemes #
Congo ships with a number of colour schemes out of the box. To change the basic colour scheme, you can set the
colorScheme theme parameter. Refer to the Getting Started section to learn more about the built-in schemes.
In addition to the default schemes, you can also create your own and re-style the entire website to your liking. Schemes are created by by placing a
<scheme-name>.css file in the
assets/css/schemes/ folder. Once the file is created, simply refer to it by name in the theme configuration.
Congo defines a three-colour palette that is used throughout the theme. The three colours are defined as
secondary variants, each containing ten shades of colour.

Now whenever you make a change, the CSS files will be rebuilt automatically. This mode is useful to run when using
