title: Set default css of input type button
body: <p>I am applying a background image on input type button. for this i have written my code in style.css. But now i want that button will look like as it is default, but my restriction is that i can not delete css style from style.css. But i can override it in other css style1.css.
  so how can i override this?</p>
  
  <p>style.css</p>
  
  <pre><code>button
  {
  background:red;
  }
  </code></pre>
  
  <p>if i override like this it shows nothing.</p>
  
  <p>style1.css</p>
  
  <pre><code>button
  {
  background:none;
  }
  </code></pre>
