body: <p>How to make a cross (X) only in CSS3, to use as a close button?</p>
  <p>I've been searching for a long time, and cannot found how....
  When I look at source code on a website using it, there's always something weird which makes the code I take unusable.</p>
  <p>The X button I want: <a href="http://tympanus.net/Tutorials/ThumbnailGridExpandingPreview/" rel="noreferrer">http://tympanus.net/Tutorials/ThumbnailGridExpandingPreview/</a></p>
  <p>When you click an image, this is the cross on the right:</p>

  <p>I think this would be great if somebody can post a simple universal CSS code to make a simple X cross in CSS3.</p>
