title: Which is the better way to visually hide things, clip: rect(0, 0, 0, 0) or visibility: hidden?
body: <p>Recently, I saw some tricks on hiding things. What I'm curious about is what's the difference between <code>clip: rect(0, 0, 0, 0);</code> and <code>visibility: hidden;</code>, while both can hide things and remain the space in the same time. </p>
  
  <p>Also, is there any difference between using <code>clip: rect(0, 0, 0, 0);</code> and <code>clip: rect(1px, 1px, 1px, 1px);</code>?</p>
