[DJW:] My feeling is that this would be taking styled HTML well beyond what it is appropriate for. HTML was designed as a navigation tool for finding more specific formats, not as a multimedia animation and page description language. Note that a properly designed page will tend to naturally display things in the order in which they should be read, because a well designed page will be in the logical reading order when nothing is positioned and tables are ineffective. Deferring cosmetic detail in favour of signicant detail is likely to result in the page being abandoned before the cosmetics have loaded, making it better not to have used them in the first place (something I never really understand is why people put in so many cosmetics when for most of the time that a navigation page is on display it is incomplete, and therefore ugly). Accessibility considerations, and the effect of caching, mean that you cannot rely on images, or their order of presentation, to convey critical information. Also note that HTTP 1.1 clients are supposed to only maintain two connections at a time, so will display images in succession, and probably in the linearised order of the page. In fact, pipelining of requests will mean that maybe up to thirty image requests will already have been issued by the time the end of the HTML is reached, so any display me first image at the end will have to wait for all the images in the pipeline, or no requests can be made until the whole page has been read, or the pipeline will have to be aborted and restarted. > this allows more *interesting* control > [DJW:] I suspect you should be looking at SMIL and or SVG, or proprietory animation formats.
