title: Creating css full screen layout
body: <p>Endles trying to create a css layout  </p>
  
  <pre><code>&lt;div id="act"&gt;&lt;img src="img/home01.jpg"&gt;&lt;/div&gt;    
  &lt;div id="buttons&gt;&lt;/div&gt;
  </code></pre>
  
  <p>img "home01" should fit the screen. No scrolls, no whitespaces, no overflows, whatever is the monitor size and whatever is the img original size. </p>
  
  <p>div buttons should be available for clicking, i.e. in front of the img "home01" (higher z-index) and centered hor&amp;ver on the screen.<br>
  Please help.</p>
