title: detection of height doesn't work
body: <p>I have this simple script:</p>
  
  <pre><code>var o = document.getElementById("content");
  
  if (o.clientHeight == "372") {
    o.style.height = "328px";
    o.style.marginBottom = "44px";
  
  } else {
    o.style.height = "214px";
    o.style.marginBottom = "32px";
  }
  </code></pre>
  
  <p>but somehow the ELSE always executes, even if the initial height of my div is 372px...
  can anyone help me?</p>
