“A minute to learn . . . A lifetime to master.” That phrase might feel a little trite these
days, but I still like it. It was popularized in modern times by being the tagline for the
board game Othello. In Othello, players take turns placing white or black pieces onto a
grid. If, for example, a white piece is played trapping a row of black pieces between
two white, all the black pieces are flipped and the row becomes entirely white.
Like Othello, it isn’t particularly hard to learn the rules of CSS. You write a selec-
tor that attempts to match elements, then you write key/value pairs that style those
elements. Even folks just starting out don’t have much trouble figuring out that
basic syntax. The trick to getting good at CSS, as in Othello, is knowing exactly when to
do what.
CSS is one of the languages of the web, but it isn’t quite in the same wheelhouse as
programming. CSS has little in the way of logic and loops. Math is limited to a single
function. Only recently have variables become a possibility. Rarely do you need to con-
sider security. CSS is closer to painting than Python. You’re free to do what you like
with CSS. It won’t spit out any errors at you or fail to compile.
The journey to getting good at CSS involves learning everything CSS is capable of.
The more you know, the more natural it starts to feel. The more you practice, the
more easily your brain will reach for that perfect layout and spacing method. The
more you read, the more confident you’ll feel in tackling any design.
Really good CSS developers aren’t deterred by any design. Every job becomes an
opportunity to get clever, a puzzle to be solved. Really good CSS developers have that
full and wide spectrum of knowledge of what CSS is capable of. This book is part of
