title: How to create a CSS style which override another CSS style
body: <p>I have 2 CSS styles which pretty much the same except one specific 'width' and the other does not. How can I create a CSS style which inherits another CSS style but override a property?</p>
  
  <pre><code>  .FirstStyle
      {
          margin: 0px 0px 0px 8px;
          position: relative;
          display: inline-block;
  
          height: 29px;
          width: 5px;
  
          float: left;
      }
  
  
      .SecondStyle
      {
          margin: 0px 0px 0px 8px;
          position: relative;
          display: inline-block;
  
          height: 29px;
  
          float: left;
      }
  </code></pre>
