title: Resizing font in textarea without increasing textarea size
body: <p>I was messing around with some Jquery to have a slider control the size of font in a text area and used something like:</p>
  
  <pre><code>...  
  slide: function( event, ui ) {
      $('#t_area').css("font-size", ui.value + "px");
  }
  ....
  </code></pre>
  
  <p>within the function to control the slider.  I noticed that even when I didn't have text in the textarea, it still increased in size when I moved the slider (and also grew too large when there was text in it.)  So I was wondering if there was a way to increase the size of the text without having that side effect?</p>
  
  <p>Thanks</p>
