Challenge: Learn How the CSS @keyframes and animation Properties Work

Link to the challenge:

Hi @Alcides1987.

Your values for the keyframes query aren’t actually inside of the query; you have a closing bracket before the background color definitions.

@keyframes rainbow 

} <- here

If you edit the query to include the background color values, that should fix it.

Hope this helps!
