Using Important

So I have read the other comments and I’m still stuck on the last part, turning the text pink

Your code so far

<style>
  body {
    background-color: black;
    font-family: Monospace;
    color: green;
  }
  #orange-text {
    color: orange;
  }
  .pink-text {
    color: pink!important;}

  .blue-text {
    color: blue;
  }
</style>
<h1 id="orange-text"class="blue-text pink-text"style="color: white">Hello World!</h1>

I managed to sort it by swapping the style color to pink, thanks for your reply.
