title: My CSS changes with the screen size
body: <p>I have seen the option of loading different css files[called responsive web designing] for different screen sizes. But I want to know if there is some other way through which I can keep the CSS uniform. 
  I have to adjust the width of a title bar that should be of the same size as browser window with some margin-right</p>
  
  <pre><code>&lt;toolbar width="some px value" margin-right="some px value"&gt;
  </code></pre>
  
  <p>I need some spacing at the end of the browser screen
  Can I somehow get the current width of the browser screen and thus adjust my titlebar accordingly</p>
