I am reading: http://css-tricks.com/textarea-tricks/

In part one:
"1. Image as textarea background, disappears when text is entered." the second screen code is:
$('textarea')
  .focus(function() { $(this).css("background", "none") })
  .blur(function() { if ($(this)[0].value == '') { $(this).css("background", "url(images/benice.png) center center no-repeat") } });

Open in new window


I have placed this in css section in the code below but it doesn't work. It doesn't work because after I enter some text to the textarea control and exit it, the image "Be nice!" still is seen?

Question: What do I need to do for the image disappear once I enter some text into the text area?

I know with html5 place holder is the best for this purpose. But I want to handle the image and make sure I am correct in placing this code in css section.

Thank you.
