The #1 Javascript Pop Up made by Paul Engel

TopUp preset

Specifying a TopUp preset is just like specifying style attributes to a CSS selector in your stylesheet. The great advantage of using presets is that it provides you to keep your HTML entirely(!) clean.

Just call TopUp.addPresets() with a hash as parameter.
The key of each entry has to be a CSS selector and the value has to be a hash of toptions.
