title: How to set transparent background in HTML5 element
body: <p>I want to set the opacity of an element to 0. Now if i do this, all the content of the element will inherit this property. I don't want this, i just want the background to get the opacity 0 while the content (the text for example) stays visible</p>
  
  <p>Any clues ?</p>
  
  <p>Thanks.</p>
