FWIW, authors can use that approach today. Whether they should is another thing. In practice this won't work well because it seems that most UAs flat-out ignore media=braille and media=speech CSS. So if you set your paragraph containing a summary to display:none for media=screen, a screen reader like Jaws will probably not present that paragraph to the user either. Another thing is that, frankly, I cannot imagine that authors would bother to write up a 'visual' summary and then go through the CSS hoops to suggest it be hidden in certain media. If they don't bother to provide summary attributes, why would they bother using a harder method? (Harder, because now they suddenly need to know CSS, understand CSS media, write and maintain more complex code.) HTML 4's summary attribute is much easier to author. At the same time authors will not provide such a summary and *not* bother with CSS trickery, because that results in redundant information for visual users. So even the principle question of whether we are talking about content or presentation here aside, leaving this sort of thing up to CSS doesn't seem realistic. -- Sander Tekelenburg The Web Repair Initiative: <http://webrepair.org/>
