It looks like a variable is being used to set the background color of the .red-box class. Let's improve our browser compatibility by adding another background declaration right before the existing declaration and set its value to red

Tell us what’s happening:

Your code so far


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

Check your spelling plus you need to add the rule to the .red-box class as there is where the rule you need a fallback for is applied `

Thank you for give me suggestion…
