@flowerhack, no worries - its a front end standard/philosophy we know about but hasn't been circulated at large! We try to leave the styling layer completely managed by CSS when we can, so in this case we'd toggle a class on that HTML element through JavaScript. @frrrances probably knows best what class she needs for this UI - I'd just ask her what class to  include in JQuery's .removeClass(); / .addClass(); or toggleClass(); methods.
