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;
    margin-top: 40px;
    margin-right: 20px;
    margin-bottom: 20px;
    margin-left: 40px;
  }

  .green-box {
    background-color: green;
    padding-top: 40px;
    padding-right: 20px;
    padding-bottom: 20px;
    padding-left: 40px;
  }
</style>
