title: Checking if an element is really visible to the user
body: <p>I'd like to check whether the user can see an element in the current web browser view without scrolling.</p>
  
  <p>What I've found can check whether the element is somewhere on the page.</p>
  
  <p>Another hint suggested to check the elements position but then I would need to get the dimensions of the visible window of the browser plus its <em>x/y</em> offset to <em>0/0</em>.</p>
  
  <p>I would be grateful if someone could point me to a solution that does not need JavaScript code.</p>
