title: need help to get float value of css 'font-size'
body: <p>I need help to get float value of css 'font-size'. In firefox it works perfect.
  I have trouble in Chrome, Safari, IE...
  I try to get this css value but result-less, it converts to int value. I check in two ways: with JQ and pure JS:</p>
  
  <p>My code:</p>
  
  <pre><code>alert('jq: '+$('#element').css('font-size')); // int value
  
  var labelElement = document.getElementById('element');
  var fontSize = parseFloat(window.getComputedStyle(labelElement, null).getPropertyValue('font-size'));
  alert('pureJS: '+fontSize); // int value
  </code></pre>
  
  <p>I take screenshot from Chrome, in developer tools it sees font-size in right value. </p>
