Sure, but it is not solved by GUI toolkits like winforms, which is why they are not directly comparable. And A DTP system will not gracefully adapt the layout if you change the page dimensions or scale up the font. My point is just that CSS is designed like it is because it tries to solve some particular problems. If you expect it to work like a GUI toolkit (or DTP program) you will be confused because they do not try to solve the same problem.
