Add a Negative Margin to an Element (New)

Tell us what’s happening: The green box margin doesn’t change . I’ve tried random numbers but it still stays the same.

Your code so far

<style>
  .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: 10px;
  }
  
  .red-box {
    background-color: red;
    padding: 20px;
    margin: -15px;
  }

  .green-box {
    background-color: green;
    padding: 20px;
    margin: -15px;
  }
</style>

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

Sometimes some challenges can “hang”, have you tried reloading/refreshing the page and submitting again?

Refreshed and still nothing.

Solved. I had to start a new .green-box entry
Thanks!
