Prototype - getStyle() Method

Quiz

This method returns the given CSS property value of element. Property can be specified in either of its CSS or camelized form.

Thus providing font-size and fontSize are equivalent.

Syntax

element.getStyle( property );

Return Value

Either CSS property value or NULL if it does not find a property set. Internet Explorer returns literal values while other browsers return computed values. Safari returns null for any non-inline property if the element is hidden.
