The "trick" is to employ progressive enhancements.

Also, the less CSS, the better. + no shame in using !important sometimes.

All in all, CSS requires experience

!important is like global variables

Sure they have their place, but goddamnit do some people abuse them and make huge messes with them :(

Better off repeating classnames (.foo.foo { color: pink; }) than using !important.
