Improve compatibility with browser fallback-8/1820

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.

Your code so far

:root {
–red-color: red;
}
.red-box {
background: red; /* this is the browser fallback */
background: var(–red-color);
height: 200px;
width:200px;
}


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