List Box Title formatting not working in K2 5.3?

Hi,

In a List Box, I have items in Arial 12, but the List box title stays in small unchangeable size.

In the past i've used this script INSIDE a table to change the title size, but not working in 5.3.

<script type="text/javascript">$(document).ready(function(){ $('.title').css({'font-size' : '16px','font-family' : 'arial'});});</script>

or this

<script>$(".title").css({'font-size' : '16px','font-family' : 'arial'});</script>

So i would usually add a data lable, tick literal and add the above code in an expression and bingo it would work.

The data lable would be inside a table to work.

This code used to work fine in K2 5.0 and 5.1 but doesn't seem to work in 5.3, any ideas?
