title: How to override the properties of a CSS class using another CSS class
body: <p>I am fairly new to CSS3 and I want to be able to do the following:</p>
  
  <p>When I add a class into a an element, it overrides the properties of another class used in this specific element.</p>
  
  <p>Let's say that I have</p>
  
  <pre><code>&lt;a class="left carousel-control" href="#carousel" data-slide="prev"&gt;
  </code></pre>
  
  <p>I want to be able to add a class called <code>bakground-none</code>, that will over override the default background in the class <code>left</code>.</p>
  
  <p>Thanks!</p>
