Browser fallback - background colour

Browser fallback - background colour


Tell us what’s happening:
Hi there,

Feel a bit stupid but i’m struggling with creating a fallback background colour in this challenge. I have tried adding ‘background-color: red;’ immediately before the ‘background: var(–red-color);’ line but i cannot get it to work. Any help would be great!

Your code so far

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

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