Hi guys. Im from Argentina so if my english its not excellent dont panic :slight_smile:

Your code so far


<style>
  :root {
    --red-color: red;
    
  }
  .red-box {
    
    background: var(--red-color, red);
    height: 200px;
    width:200px;
  }
</style>
<div class="red-box"></div>

Hi @Co2, welcome to the forum :smile:
I think that that the problem is this line:

It should be

background: var(--red-color);

like it was at the beginning of the challenge.
Before that, you should put another background declaration without using a variable.
So, something like this:

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

When the var is supported, the second declaration will override the first.
