I am trying to use jQuery to change the background image in a table cell, the table cell has its own class of ".active". I am using jQuery to change other elements in the same place and they all work fine so i think i must have something wrong in the syntax. the function i am using executes after a button is clicked.
background-size: 10px 10px;
border-right: 1px solid none;
the first line executes fine, i have tried the following code plus changed the picture size in every way i can think of :
can anyone point out what i did wrong?
