/*



CUSTOM FORM ELEMENTS



Created by Ryan Fait

www.ryanfait.com



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.



Visit http://ryanfait.com/ for more information.
