Override Styles in Subsequent CSS 101

Tell us what’s happening:
I can’t find out how to get the text to be blue and they are in the same h1 but it says that they aren’t

Your code so far

<style>
  body {
    background-color: black;
    font-family: Monospace;
    color: green;
  }
  .pink-text {
    color: pink;
  }
  .blue-text {
    color: blue;
  }
</style>
<h1 class="pink-text" class="blue-text" >Hello World!</h1>
