Where do the themes live?

CSS Files

Slides available at datalorax.com/talks/cascadia18

How do you contribute your own theme?

My advice

1. Start with an existing theme
2. Modify the CSS
   • Change colors!
   • Change fonts! (see here, import fonts with google fonts)
   • Consider changes to the background

Look at CSS for existing themes

Basically this

Once you've settled on a theme

1. Pull out just the parts of your theme that are different from the default theme
   • Name the css file what you want your theme to be called (keep it simple and all lower case)
2. Put all of your fonts in a separate file, called themename-fonts.css.
