We are fortunate, with one exception, as far as the cross-browser stylesheet is concerned. The height property, necessary for Explorer, will not affect Navigator. The clip property, recognized by Explorer, becomes a redundancy. The extra Navigator element, elGif , will remain, in Explorer, a real but empty element, since we will not write to it in our script. Unfortunately Navigator chokes on the filter property, although all other unknown properties are properly overlooked.
Navigator ignores it, properly.
Since we want to keep all the browser-specific code together, in the script, and the HTML as clean as possible, we will choose this second option. The filter property is a string corresponding to filters set for that element. We'll insert it into our script, further down. The HTML insertion of the fader elements remains in its Navigator version. . . There is not much to be said about the cross-browser script.
