 ...meaning that any CSS selectors beginning with `body.dark` or `body.light` will only apply when the respective mode is active. A good place to start is by separating any color rules — your background, text, links, etc. — into a different section of your CSS. Using [SASS or SCSS](https://sass-lang.com/) makes this a whole lot [easier with nesting](https://sass-lang.com/guide#topic-3) but is not required; this was written with a [KISS](https://getyarn.io/yarn-clip/embed/eed08f4f-d1c9-4cc0-b041-f280a5dbf0a5?autoplay=false) mentality.
