Using Checkboxes to Make Forms More Friendly

Checkboxes default to being checked when they are active. Many web documents have these types of controls. You can change their appearance to make them more rounded and make the labels clear for your users. Checkboxes differ from radio buttons because you can select multiple checkboxes simultaneously.

Note: Radio buttons are similar to checkboxes, but with an important distinction - same-named radio buttons are grouped into a set in which only one radio button can be selected at a time, whereas checkboxes allow you to turn single values on and off. Where multiple same-named controls exist, radio buttons allow one to be selected out of them all, whereas checkboxes allow multiple values to be selected.
