Global traits, local components

The idea is to combine the best bit of global styling (reuse, small payload) and local styling (total isolation, first-class React syntax)

This is combined with the concept of traits: you can think of them as permitted property/value pairs. Instead of every component being able to have every CSS property available to it, you can reduce your permitted set to X font families, Y font-size + line-height pairs, Z foreground/background colour pairs, W padding amounts. This is based off my work using amcss on real projects — traits were the single key feature that kept me using AM.

The one-sentence explanation: A site defines a set of permitted visual features, all components are simply a combination of those features

Few Tricks on Compressing Js13k Entry

Most important detail: in js13k entry 13k stands for zipped entry size. And this detail makes js13k differ from other code golfing compos.

Last year winner entry uncompressed size was about 70k. 70 kilobytes! In js1k you have a month to minify 1k, so how much time would it take to minify 70k? Nope, you have only 1 month. So it's very unlikely one will manually golf the entry. And this is the other thing that makes js13k special: no hardcore manual "hell yeah I've stripped one byte!" golfing.

About Sass and Gzip

Hey guys! I have a question regarding Sass usage and Gzip compression. If anyone knows something, be sure to share. :)

A quick reminder

It's good practice to use Sass @extend rather than including mixins when possible because of the way Sass handles @extend. To put it simple, it doesn't take the CSS content from the extended selector to place them in the extending one. It works the other way around: it takes the extending selector and append it to the extended selector.
