Recently as I develop with jQuery, I’ve been trying to either use jQuery UI ThemeRoller supported plugins or somehow tweak existing jQuery plugins to support the ThemeRoller classes. Note: There are many plugins out there that already support ThemeRoller (and you can find a list I’ve compiled in my previous Quickly Testing Various jQuery UI Themes on Your Website post). Out of all the jQuery tooltip plugins I’ve seen, I prefer the qTip implementation. The tooltips look good and it is easy to use. There are several themes that are supported out of the box and you can also tweak the styles if you don’t like the baked in ones.
