I've been asked a few times if Dimensions would provide a method for getting the scrollbar width.

A common question on the jQuery mailing list is: "Where is the hasClass method?". jQuery has a very flexible method named is. This method takes an expression to test against. For example you could see if a particular element is a form element.

    .remove();

This chain simply inserts a <p> tag before the selected element and then removes that element resulting in a replacement. You [...]
