No, it's not. HTML doesn't define its presentation, and CSS only contains an appendix that's an example of how one might present HTML (with a bunch of mistakes in it). The HTML DTD does have entities called %block and %inline, but those refer to what elements are allowed to contain other elements, not to the display type. > Now about how it's coded in Gecko: I think it gets it from the appropriate > DTD (which varies according to the HTML version each page uses), or from > some default DTD if there is no <!DOCTYPE at the start of the document, but > that's only a guess on my part. Gecko doesn't parse DTDs for HTML, nor do any other frequently used Web browsers. That said, this is a list for Mozilla developers. Given your level of experience in Mozilla development, you're probably better off here doing relatively more reading and less posting. Otherwise Mozilla developers who participate in this list will spend all their time correcting misinformation and be unable to find the real Mozilla development discussions on the list, which will cause the Mozilla project to become less open because there aren't any usable public discussion forums for developers. -David -- L.
