It’s XAML to win the day, just wait til Microsoft push it with the platform! ;)
They’ve done it before and now they’ll do it again.

Bet my career on it.

There’s nothing wrong with HTML at the moment.

But maybe we need to think ahead. I’d like to see more features but they are more related to the browsers rather than being HTML specific. For example, instead of using AJAX hacks to create a calendar/date drop down (like in Google Calendars) when a user has to type in a date - as a part of forms, it could have it’s own drop down date-tag. Then you could style it like you want via CSS.

But then again, introducing new tags like these will be dangerous for compatibility.

It’s pretty much impossible to build a mildly complex layout without resorting to CSS hacks or HTML tables—both are being used how they weren’t originally intended.

The funny thing is that I doubt that cars were originially developed for killing people, but they sometimes are used specificially for that. :)

Most browsers seem to have CSS turned on, but since Firefox allows me to turn it on/off at will (using Chris Pederick’s WebDeveloper add-in), I do. That’s the nice thing. If one wants a web site to be valid for older browsers and newer browsers, they can use a combination of these techniques dependent upon the browser’s agent information. Thus, the web page can be custom built for each web browser as necessary (using appropriate server side scripts of course).
Imagine what those “poor” text only browsers are like … uuuggghhh, my brain can’t take that. Think about the crap they have to weed through. :-P

no blinking!

….wait a minute

Perhaps HTML could be replaced completely by XML - no prespecified tags, you just organize the data how you want with custom tags. Then, CSS could be replaced with a more powerful layout language - kind of a mix between current HTML and CSS with a dash of a scripting language. This way it can take the XML data and have complete control on how it is displayed to the user.

This will never happen though. There is too much momentum behind the current technologies and it takes ages to make significant changes (will CSS 3 ever come?). On the bright side, server-side technologies seem to be moving faster which helps overcome some of the problems with the client-side languages.
