Improve Compatibility with Browser Fallbacks II

Tell us what’s happening:

I cannot move a head of Basic CSS: Improve Compatibility with Browser Fallbacks

The instructions say to
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.

This is my code, what is wrong?

<style>

:root {

–red-color: red;

}

.red-box {

background: var(–red-color, red);

height: 200px;

width:200px;

}

</style>

<div class=“red-box”></div>

Your code so far


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

You didn’t follow the instructions.

Let’s improve our browser compatibility by adding another background declaration right before the existing declaration and set its value to red.

Like this

<style>

:root {

–red-color: red;

}

.red-box {

background: var(–red-color, red);

height: 200px;

width:200px;

background: var(–red-color, red)

}

</style>

<div class=“red-box”></div>

Read the description and instructions carefully. Exactly repeating the same line does not change any behavior.

This did work. Is there more information on this?

.red-box {
background: red;
background: var(–red-color);

height: 200px;
width:200px;

Thank you,

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.

Thank you for understanding.

You have to change background part as per instruction given.
