Question

http://jsfiddle.net/aBaw6/2/

This demo does not add class when you hover a list item.

What am I doing wrong here?

$("li").hover(
  function () {
    $(this).addClass('hover);
  }, 
  function () {
    $(this).removeClass("hover");
  }
);

html

<ul>
    <li>Milk</li>
    <li>Bread</li>
    <li>Chips</li>
    <li>Socks</li>
</ul>

css

.hover{
    color:green;
    font-size: 20px;
}

Thanks in advance.

Your JavaScript was badly formed:

$("li").hover(
  function () {
    $(this).addClass('hover);
  }, 
  function () {
    $(this).removeClass("hover");
  }
);

Should be:

$("li").hover(
  function () {
    $(this).addClass('hover');
  }, 
  function () {
    $(this).removeClass('hover');
  }
  );

If you click on the JS Lint button to the top of the screen it would’ve told you this (this isn’t intended as a criticism, just a note for your future use of JS Fiddle).
