Hi. Does anybody know if there is a way to format the appearance of a check box or radio button using css.
No. Appearance of form elements and how CSS is applied to them is not defined in the specification and is left up to the whim of the browser maker, NOT the developer. Any CSS you try to apply will only break it even worse cross-browser; see the train wreck that happens to inputs, selects and textarea's when you null margins and padding on all elements... ... or what Safari does with form elements.
