title: CSS combining % and px width
body: <p>I've a div with width in percentage. Is it possible to align two divs inside it (on left and right) so that the left div has fixed width defined in the px and margin to right in percentage, while the rest of width goes to the right div.</p>
  
  <p>For example consider this:</p>
  
  <pre><code>&lt;div class="box"&gt; 
  
      &lt;div class="left"&gt;
  
      &lt;/div&gt;
  
      &lt;div class="right"&gt;
  
      &lt;/div&gt;
  &lt;/div&gt;
  
  .box{
      width:100%;
      border:1px solid red;
      overflow:hidden;
  }
  
  
  .left{
      float:left;
      margin-right:5%;
      width:100px;    
  }
  
  
  .right{
      Problem..
  }
  </code></pre>
