Improve Compatibility with Browser Fallbacks.,,

HTML-CSS
1

Tell us what’s happening:
" Your .red-box rule should include a fallback with the background set to red immediately before the existing background declaration."
Is this what it is wanting?
Can someone explain how this is done

Your code so far


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

your first style inside your .red-box should just be

background:red;

That way when your style with variable fails, it will resort back to the previous line.
