Why xhtml over html?

I currently know html pretty well and I am thinking if it is worth it to learn xhtml. What are some pros and cons of xhtml compared to html?

Actually the pages are loading faster with xhtml, and it is supposed to be the next generation of web sites.

I haven't made any xhtml project till now so I can't tell you more

i code about 95% of my client projects in XHTML, and I don't think it's difficult or time-consuming to learn at all. If you can handle HTML4, XHTML should be no problem.

Ok, I'm going to learn it then. :D  The book I got teaches both but I just used html.

Well if you know html then xhtml is pretty much the same thing. The tags are just a bit different but you won't really have to "learn" it. You just need to make sure you know the valid way of coding it.

I didn't even know there was much of a difference. There is so much about web design I need to learn, it is quite discouraging :(

Just have in mind, that even people in the Nasa's staff have started from zero once :)

I definitly recommend XHTML, search engines can crawl it with more ease, it almost always displays better, and generally loads faster. Also, XHTML isn't hard at all to learn or to follow.

The difference in the speed is huge.

Try this: Visit a category of this forum, and open in another browser the same category in the RSS form of it (which is xhtml) The same queries will run in the database, but the speed is almost double when you open the html page.
