Tell us what’s happening:
What to do?
Tried these things but non of them are working:-
i) Adding background with red.
.red-box {
background: red;
background: var(--red-color);
height: 200px;
width:200px;
}
//this is not working.
ii) Adding callback as told in the previous lesson just before this.
.red-box {
background: var(--red-color, red);
height: 200px;
width:200px;
}
//this is also not working.
The console shows this as an output.
=> Your .red-box rule should include a fallback with the background set to red immediately before the existing background declaration.
Your code so far
<style>
:root {
--red-color: red;
}
.red-box {
background: var(--red-color);
height: 200px;
width:200px;
}
</style>
<div class="red-box"></div>
