Failed test case

Tell us what’s happening:
It was given that i had to apply padding of 1.5 em on the “red-box” class but after doing so the test cases are failing. I even went through the video solution which did the same thing.

Your code so far

.injected-text {
  margin-bottom: -25px;
  text-align: center;

.box {
  border-style: solid;
  border-color: black;
  border-width: 5px;
  text-align: center;

.yellow-box {
  background-color: yellow;
  padding: 20px 40px 20px 40px;

.red-box {
  background-color: red;
  margin: 20px 40px 20px 40px;
  padding : 1.5em ;


.green-box {
  background-color: green;
  margin: 20px 40px 20px 40px;
<h5 class="injected-text">margin</h5>

<div class="box yellow-box">
<h5 class="box red-box">padding</h5>
<h5 class="box green-box">padding</h5>

You have an unnecessary space after the padding element, remove it and you’re doing fine.

This kind of problem will be ongoing. In order to scale
the debugging solution you need to automate your syntax
checking with a linter. For example the solutions noted
below could be found with which has
a demo page that finds all the errors in your css above,
not just the one error that fixed this problem for the
freecodecamp test case.
