Building and updating the custom theme

Reveal.js has multiple built-in themes but what's better is you can customize your own theme. Trino presentations use our own branding and coloring already, but they can always be improved. Here are the steps to update them.

We've created trino-theme.scss from the .scss files in /reveal/css/theme/source. It will be automatically compiled from Sass to CSS (see the gulpfile) when you run npm run build -- css-themes. To see all exposed variables to use in the scss files, reference the /reveal/css/theme/template/exposer.scss file.

Note For more general css changes to the presentation that don't directly apply to the Trino Reveal theme, put that CSS in /css/trino.css

Each theme file does four things in the following order:

1. Include /reveal/css/theme/template/mixins.scss Shared utility functions.

2. Include /reveal/css/theme/template/settings.scss Declares a set of custom variables that the template file (step 4) expects. Can be overridden in step 3.

3. Override This is where you override the default theme. Either by specifying variables (see settings.scss for reference) or by adding any selectors and styles you please.

4. Include /reveal/css/theme/template/theme.scss The template theme file which will generate final CSS output based on the currently defined variables.
