Responsive Design with Bootstrap Fluid Containers

Tell us what’s happening:

Hey, I’m kinda stuck on nesting all the HTML in a dev element with class “container-fluid” I made the class and tried to nest the dev but no luck. I figured It’s because there is nothing in the class container-fluid? Any help? Thanks.
Your code so far


     
<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/bootstrap/3.3.1/css/bootstrap.min.css"/>

<style>
  .red-text {
    color: red;
  }

  h2 {
    font-family: Lobster, Monospace;
  }

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

  .thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
    border-radius: 50%;
  }

  .smaller-image {
    width: 100px;
  
      
    }
  
   .container-fluid
    {
      
  
  }
</style>
