| The only things you may need to change in this file are the following |
| variables: checkboxHeight, radioHeight and selectWidth (lines 24, 25, 26) |
| |
| The numbers you set for checkboxHeight and radioHeight should be one quarter |
| of the total height of the image want to use for checkboxes and radio |
| buttons. Both images should contain the four stages of both inputs stacked |
| on top of each other in this order: unchecked, unchecked-clicked, checked, |
| checked-clicked. |
| |
| You may need to adjust your images a bit if there is a slight vertical |
| movement during the different stages of the button activation. |
| |
| The value of selectWidth should be the width of your select list image. |
