Tell us what’s happening:

Your code so far


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

There is an empty line for the .red-box selector, you need to add something there. Even if you do that right, if you change anything else you will not be able to pass tests

A browser fallback is needed when the browser doesn’t support variables, and what the browser needs is a declaration that doesn’t use variables - how would you set the background if you didn’t know about variables?
