To customize your site’s aesthetic, open `_sass/custom/custom.scss` in your editor to see if there is a variable that you can override. Most styles like fonts, colors, spacing, etc. are derived from these variables. To override a specific variable, uncomment its line and change its value.
For example, to change the link color from the purple default to blue, open `_sass/custom/custom.css` and find the `$link-color` variable on line `50`. Uncomment it, and change its value to our `$blue-000` variable, or another shade of your choosing.
To add your own CSS at the end of the cascade, edit `_sass/overrides.scss` to add in your own custom CSS. This will allow for all overrides to be kept in a single file, and allow for any upstream changes to still be allowed.
For example, if you'd like to add your own styles for printing a page, you could add the following styles.
