runtimeStyle | NN n/a IE 5(Win) DOM n/a
The runtimeStyle object (a property of all HTML element objects in IE 5 and later for Windows) acts like a super-powerful style object: setting any of its properties overrides that property's settings that may exist in explicitly coded style definitions. Thus, it overpowers global, imported, linked, and inline style definitions. This object shares nearly the same long list of properties and methods with the style object.
