Learn CSS Colors by Building a Set of Colored Markers - Step 78

I’m having trouble figuring out how to make a new selector that targets both the “cap” and “sleeve” classes.

  **Your code so far**
/* file: index.html */
<!DOCTYPE html>
<html lang="en">
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Colored Markers</title>
  <link rel="stylesheet" href="styles.css">
  <h1>CSS Color Markers</h1>
  <div class="container">
    <div class="marker red">
      <div class="cap"></div>
      <div class="sleeve"></div>
    <div class="marker green">
    <div class="marker blue">
/* file: styles.css */
h1 {
text-align: center;

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

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

.cap {
width: 60px;
height: 25px;

.sleeve {
width: 110px;
height: 25px;
background-color: rgba(255, 255, 255, 0.5);


.red {
background: linear-gradient(rgb(122, 74, 14), rgb(245, 62, 113), rgb(162, 27, 27));

.green {
background: linear-gradient(#55680D, #71F53E, #116C31);

.blue {
background: linear-gradient(hsl(186, 76%, 16%), hsl(223, 90%, 60%), hsl(240, 56%, 42%));

Look back at this challenge:

Hey! In CSS there are many types of selectors which you can use to target very specific types of elements in your HTML.

for example, if you wanted to select a button element which is inside of a div you would do something like this:

div button{
    color: red;

// if your  HTML looks like this.

     // this button's color will change
    <button> inner button</button>

// this button's color will not change
<button> outer button</button>

In the same way, when you create a selector using two class selectors without a space for example:


In english this would loosely translates to: “Select any element that has the class of .cap as well as .sleeve”

for example:

// this button will be selected
<button class="cap sleeve"> </button>

which is not what you want. To complete this challenge, all you need to do is put a comma between the two selectors which will change its meaning to : “Select any elements that have the class of cap or sleeve”.

Hope this helps :smile:
p.s. if you would like to take a deep dive in the CSS selectors world, i would advise you to go through “Grouping Selectors” section in this article.
