title: Is the 'frosted glass' effect implementable with CSS only at this time?
body: <p>The frosted glass effect (where an overlay both blurs and tints what is below it) is a common UI element in iOS. </p>
  
  <p>Is there currently anyway to implement that with CSS? There are a lot of questions pertaining to this, but they are limited in what they can do. They typically are limited to putting an overlay over an image--rather than a completely rendered UI.</p>
  
  <p>So, to be clear, I'm not looking for a way to blur an image by itself, but a way to blur the UI below an element. So say I have an HTML form with HTML buttons and HTML text, and I want to place a div above them all so that whatever is below looks blurred. And then I can perhaps scroll what is below and as elements come in and out of the overlay, they are blurred only while under the div.</p>
  
  <p>My understanding is that the answer to this is <strong>no, this is not currently possible with CSS</strong> but I'm also a bit rusty on the new bells and whistles...</p>
