title: width:100% vs max-width: 100%
body: <p>Could width:100% and max-width:100% be used interchangeably if any of them is used just once?</p>
  
  <p>For example I get the same results with:</p>
  
  <pre><code>img{
      width:100%;
  }
  </code></pre>
  
  <p>and with:</p>
  
  <pre><code>img{
      max-width:100%;
  }
  </code></pre>
  
  <p>Am I missing something here?</p>
