In this lesson from freeCodeCamp's Applied Visual Design section, we look at pseudo-class selectors. Using pseudo-class selectors for styling is a helpful tool to learn. We can use the ":hover" pseudo-class during the hover state of an anchor elemnt. Using ":hover" can allow us to customize our site's links to be a customized color scheme. Look up other pseudo-class selecors to learn other cool things you can do during specific states and events.
