CSS The Selectors Solution

Here is how I made the button change colors when active: .button:active { background-color: red; } What's wrong?

Can someone please explain why this is a bad idea? I guess it would change all the buttons and this might not be a good thing? Thank you!

Kate Wilson — normally you'd set "best answer" on the one that helped resolve the question! :see_no_evil!:

This would only change the active color on the items you give the class "button" to. It's not a "bad idea" from the standpoint of overall design, but this particular exercise was to practice creating selectors for existing HTML (and not changing the HTML itself).

So since this technique requires altering the HTML to add the class, it's not within the scope of this practice exercise.
