“#1: Everything you know is wrong… sort of; #2: It’s not going to look exactly the same everywhere unless you’re willing to face some grief… and possibly not even then; #3: You will be forced to choose between the ideal and the practicable; #4: Perfection is not when there’s nothing to add, but when there’s nothing to take away; #5: Some sites are steaming heaps of edge cases; #6: Longer lead times are inevitable; #7: Coherent and sensible source order is the best of Good Things; #8: Descendant selectors are the beginning and end of genuinely powerful CSS rules; #9: In the real world, stylesheet hacks will get your project across the finish line; #10: Working around rendering bugs is like playing Whack-a-Mole; #11: When you’re drowning in CSS layout problems, make sure of the width and height of the water, float without putting up a struggle, and get clear of the problems; #12: Background images will make the difference between the plain and the tastefully embellished.” (Ben Henick – A List Apart)
