Learn CSS Colors by Building a Set of Colored Markers - Step 49

I looked up the help for this one and it seems others have had this issue but I don’t see how it was resolved. I believe my answer is correct:
.red {

Step 49

You’ve learned a few ways to set flat colors in CSS, but you can also use a color transition, or gradient, on an element.

A gradient is when one color transitions into another. The CSS linear-gradient function lets you control the direction of the transition along a line, and which colors are used.

One thing to remember is that the linear-gradient function actually creates an image element, and is usually paired with the background property which can accept an image as a value.

In the .red CSS rule, change the background-color property to background.

      <div class="marker green">
      <div class="marker blue">

h1 {
  text-align: center;

.container {
  background-color: rgb(255, 255, 255);
  padding: 10px 0;

.marker {
  width: 200px;
  height: 25px;
  margin: 10px auto;

.red {

.green {
  background-color: #007F00;

.blue {
  background-color: hsl(240, 100%, 50%);

Challenge: Learn CSS Colors by Building a Set of Colored Markers - Step 49

Link to the challenge:

Pretty sure it’s asking for:

Background-color: background;

that didn’t work :frowning:

you’re not supposed to copy. You’re supposed to replace the value with something that makes sense.

I have no idea what that means. :grimacing:

okay, what do you think this step is all about?
(what is the effect you are going for , or how do you know that you have done it correctly?)

I realize now that they wanted me to create a whole new property that was “background” and not “background-color”. @hbar1st thank you for asking the questions that make me think!
