Since the non-pseduo a selector sort of suggests using hex, I figured I’d be fancy and use #00F for the a:hover pseudo selector. However, it is not recognized as correct. Not a big deal, but should probably be fixed since prior lessons explicitly spend time teaching hex and rgb.
Correct, but not accepted:
<style>
a {
color: #000;
}
a:hover {
color: #00F;
}
</style>
