html/css is the only languages I know and I want to pull out my hair.
Even the most SIMPLE thing, such as centering an element has 100 different ways to do it, each one screwing over some minority user base (commonly Safari).
The 90% of users have a browser that is BROKEN, leading all layouts to be filled with archaic hacks (like adding a "_" before tags) to make the layout work.
Then on top of this, w3 setups validation standards to such a point that you have to be a CSS master and know all the inside hacks to make a good layout.
Often I get the impression people are saying: "I want to use to use CSS because it is the future, but WHY CAN'T IT JUST WORK!"
I know its not CSS's fault, but if you want me to make a pure CSS layout, give me some tools to make it happen so I don't spent all day making some floating/negative margin'd/macgyver'd travesty of coding to make it work.
ARRRRRRRHGHHGHGHGHGH.. I'm going back to tables...
