The HTML 5 draft did not become a formal standard
|
<br />Yesterday I saw at W3C that the new HTML 5 draft (Working Draft) was released on June 10th. I took a quick look at the new version documentation it provided and made some notes: The HTML 5 draft did not become a formal standard <br />Quote: Publication as a Working Draft does not imply endorsement by the W3C Membership. Publishing as a "Draft" does not imply endorsement (support) by W3C members. The HTML 5 specification will not be considered finished before there are at least two complete implementations of the specification. The HTML 5 specification will not be finalized until at least two software implements it. XHTML 1 was released in 1999, but it took two or three years to gain full support, and it was only recently, nearly a decade later, that it was fully promoted. So it will take some time before HTML 5 is supported (especially by that "non-mainstream" browser). According to the schedule of the W3C HTML working group, there will be no official finalization until 2010. A surprisingly simple DOCTYPE declaration <!doctype html> It's that simple, haha. Also, there is no distinction between uppercase and lowercase. It is worth mentioning that the specification requires that if this DOCTYPE is declared, the so - called "custom HTML syntax" can be used, that is, the previous HTML syntax that does not require tag closing. At the same time, it still allows XML format syntax like XHTML , in which case you need to declare the DOCTYPE of the XML document instead of the above. Forward Compatibility The HTML 5 specification does not have "deprecated" elements because on the one hand it requires designers not to try certain elements, but on the other hand it requires browsers to support these elements. In this case, my intuition is that it is intended to support all previous web pages written in HTML or XHTML . This is a blessing for designers, as they are no longer restricted by the strict syntax of XHTML . Deleted elements <br />Of course, these elements are relative to HTML 4, but it can also be seen that HTML 5 is not a simple regression to HTML 4. It still adheres to some important spirits of X HTML , such as pure interface presentation elements should be abandoned and CSS should be used. The following elements are discarded because their effect is purely presentational and therefore better handled by CSS: basefont / big / center / font / s / strike / tt / u The following elements were discarded "because their usage affected usability and accessibility for the end user in a negative way": frame / frameset / noframes The following elements were discarded "because they have not been used often, created confusion or can be handled by other elements": acronym/applet/isindex/dir What I want to explain here is that acronym is recommended to be replaced by abbr. But it seems that in IE, abbr is not as easy to use as acronym. For details, see the HTML test document at http://www.mikkolee.com/3. Use object instead of applet. This label has long been abandoned. However, when I was learning HTML , every book mentioned this applet. At that time, everyone was full of longing for Java applet, but now it has quietly withdrawn from the stage of history, which is quite emotional. isindex and dir. I won’t talk about these two here, as they are no longer recommended in HTML 3. More new elements HTML 5 introduces many new elements, which I will not list here. Please see http://www.ibm.com/developerworks/cn/xml/x-html5/.
