Mozilla Branches For 1.0 RC1
At the end of last month, the Mozilla Project closed the tree for what will become Mozilla 1.0. Now jkeiser writes "Mozilla has branched for 1.0 RC1, which is the first last step to a final Mozilla 1.0! Mozilla has spent four long years getting the browser standards-compliant, fast and solid. Cross your fingers for a rockin' final release around the corner." Reader whovian points to the just-modified roadmap, too.
RC1 comes out tentatively this week (I'm on the build and release team).
There is a big fix for DHTML performance that, while working well, is too big a risk this close to 1.0 (tracking bug #21762) so is currently targeted at 1.0.1.
Just because you can't, doesn't mean you shouldn't.
That's why the tags in the core HTML describe content like <em> indicates that the text should be displayed with emphasis as opposed to the newer <i> tag that does something similar. HTML marks content with rendering hints, but it's not designed to be able to lay out a page. It's designed to describe rendering hints on a page. Any time HTML is used to lay out a page, it's using a bastardization of tables and using tags that have been removed in HTML 4.01 strict (and are merely deprecated in HTML 4.01 transitional).
CSS (Cascading Style Sheets) is designed to lay out a page. CSS can be applied directly to an XML document (in the spec, maybe not via any tools yet), and it can also describe the page layout. I'd point you to my website that uses CSS to lay out the page, but it's currently offline, so I'll just have to send you to the W3 CSS site. If you're using a CSS compliant browser (Mozilla is the best at rendering it properly but IE works - dunno about anything else), you should notice the menu and the various links scattered about the top of the page that are defined via CSS page lay out rules.
HTML as originally designed is intended to describe sections of a document. At some point, people started developing fancy webpages and HTML 3 was born which included a lot of page lay out tags. However, more recently, with IE 5 and Mozilla, CSS and HTML have taken over for page design, meaning that newer sites can be designed using HTML 4.01 strict with CSS describing how it should be displayed. (This is the preferred, "proper" method.) Historically, HTML was originally designed to define a page structure, delinating paragraphs and lists. With HTML 4.01 it returns to the ideal, while using CSS to allow for fancy page layout.
You are in a maze of twisty little relative jumps, all alike.
