A theme controls the visual appearance of Metrici and the behaviour of browser-based components.

You can select one the buiilt-in themes for yourself from the settings page. If you are authorised, you can also set the theme for everyone in your account. This is great if you want to try a different look and feel.

As well as using the built-in themes, you can modify existing themes and create new themes from scratch.

The easiest way to do this is by using the Theme builder.
