A content slider is any element with the class 'toggle'. These elements contain 2 main attributes - 'ref', which is a JQuery selector to the element we are toggling, and 'visibility' which is the default visibility of the element referenced by 'ref', which can be either 'hidden' or 'visible'.
The content slider has 2 children which are represent the data to show depending on the visibility. One child is of class 'open' and the other of 'close'. 'open' is shown whenever the 'ref' element is hidden, and 'close' is shown whenever the 'ref' element is shown. Here is an example toggler:
<a class="toggle" ref="#respond" visibility="shown" title="Comment Submission Form Toggle">
