title: CSS Box with header
body: <p>I need the css code to create the following box:</p>
  
  <p><img src="https://i.stack.imgur.com/VjSZa.png" alt="box with header"></p>
  
  <p>This is my approach:</p>
  
  <pre><code>.content-box-gray {
  margin: 0 0 0px;
  overflow: hidden;
  padding: 10px;
  height: 15px;
  font-size: 15px;
  border-radius: 5px;
  border: 1px solid gray;
  color: #3385FF;
  }
  </code></pre>
