Computed styles and inline styles can be used together. Example 16-4 defines functions scale() and scaleColor(). One queries and parses the computed text size of a specified element; the other queries and parses the computed background color of an element.Both functions then scale the resulting value and set the scaled value as an inline style of the element. (These functions do not work in IE8 and earlier: as we’ll discuss below, those versions of IE do not support getComputedStyle( ).)
