Right. You can use xhtml 2.0, you can use flash. you can use java applets. you can use ios apps. you can use android apps. You can use director. you can use axr. you can use activex. you can even use xaml, xul or silverlight.
Go on. Use them.
I dare you. See how long you last.
or invent your own platform and see how quickly everyone switches over to it. I'm sure the only thing stopping this from happening is nobody has tried. Sure!
Why are you taking this so personally? When centering a div on vertically and horizontally is such a hassle, there can definitively be some improvements in the system. HTML lacks many semantics that would cut down on div.content or .main or any number of similar classes. CSS lacks any sort of inherit structure (like SCSS gives or taking it further with SMACSS) and quickly can become a huge mess. JS is still a terrible language with no support for basic things classes or importing.
why are you taking it so personally?
why are you reading such things in? it's totally irrelevant.
I didn't say that html/css/doesn't need improvement. that's changing the subject. The question is: why do the people here so eager to "ditch" (as in totally discard) html/css/js.
