/*

CUSTOM FORM ELEMENTS

Created by Ryan Fait

The only thing you need to change in this file is the following
variables: checkboxHeight, radioHeight and selectWidth.

Replace the first two numbers with the height of the checkbox and
radio button. The actual height of both the checkbox and radio
images should be 4 times the height of these two variables. The
selectWidth value should be the width of your select list image.

You may need to adjust your images a bit if there is a slight
vertical movement during the different stages of the button
activation.
