For browser compatibility using class that should include a fallback with the background

Tell us what’s happening:

Your code so far

.red-box {
  --red-color:red ;
.red-box {

  background: var(--red-color,red);
  height: 200px;
<div class="red-box"></div>

Challenge: Improve Compatibility with Browser Fallbacks

Link to the challenge:

All you need to do is set the background to red like you would normally do it. Put it right before/above the other background declaration (more info).

Example using padding:

:root {
 --padding-large: 20px; 

p {
  padding: 20px;
  padding: var(--padding-large);

I have already passed this, but I am pretty sure all you have to do is type in

background: red; 

Above the

background: var(--red-color,red); 

It worked I tried doing it and I passed the challenge…thank you
