Why wont this code work? I'm supposed to set a class to resize the image to 100 pixels, my browser zoom is at 100%, but it still wont run

Tell us what’s happening:

Your code so far

<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
<style>
   .smaller-image {
    width = 100px;
  }
  
  .red-text {
    color: red;
  }

  h2 {
    font-family: Lobster, Monospace;
  }

  p {
    font-size: 16px;
    font-family: Monospace;
  }

</style>

<h2 class="red-text">CatPhotoApp</h2>

<img src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back." class = "smaller-image">

<p class="red-text">Kitty ipsum dolor sit amet, shed everywhere shed everywhere stretching attack your ankles chase the red dot, hairball run catnip eat the grass sniff.</p>
<p class="red-text">Purr jump eat the grass rip the couch scratched sunbathe, shed everywhere rip the couch sleep in the sink fluffy fur catnip scratched.</p>
