I understand that CSS is not everyone's thing, but I wouldn't call it unusable. I think what frustrates many users is that while it is simple to use in a basic way, it can be difficult to use well. A lot of the burden for organization is on the user, and you do need a strategy and a knowledge of the whole application in order to use it economically. There is something of a craft to it, which I realize is not something everyone feels should be required of them. Because there are so many ways to do the same thing, more important than the immediate CSS rules is the planning and organization. CSS would not be usable if it produced errors, or if the browsers weren't so tolerant of bad CSS. You really do need to take the time and get the basics of specificity and selectors first. Some of the layout concepts can take a while to gel, and you do still need to deal with some browser differences (although it's a lot better now than it used to be). But after a while I began to appreciate how much you can get done with very little code, once you have the hierarchy of styles established for the application, it becomes very predictable. I see a lot of people hate on CSS, but very often specific issues turn out to be known and solvable. I can see why it can be seen as chaotic and unplanned, but I think it's better to think of it as very open-ended, and better to re-adjust expectations on what's needed to use it.
