This is an example of form context highlighting using CSS only

This example was inspired by this example which uses jQuery to do the same (and more, admittedly)

NOTE: this is only intended as an example, so I have not gone to great lengths to test in browsers other than Firefox and Opera - I suspect it will work in Safari/WebKit though...
