Exercise: Basic CSS: Improve Compatibility with Browser Fallbacks
Can anybody clarify what this means?
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.
The code is:
<style>
:root {
–red-color: red;
}
.red-box
{
background: var(–red-color);
height: 200px;
width:200px;
}
</style>
<div class=“red-box”></div>
I am lost here.
Thanks for any suggestions.
