Tell us what’s happening:

Your code so far


<style>
  body {
    background-color: black;
    font-family: monospace;
    color: green;
  }
  #orange-text {
    color: orange;
  }
  .pink-text {
    color: pink;
  }
  .blue-text {
    color: blue;
  }
</style>
<h1 id="orange-text" class="pink-text:color: pink !important; blue-text" style="color: white">Hello World!</h1>

Go to the CSS sheet and correct it by adding ! important to the .pink-text and remove ! important from the body. Reset your code and add only what I said you should add, no other thing.

Its better you read the tutorial again for better understanding.
