As far back as I can remember, I used Google Code Prettify to apply the syntax highlighting on code block on CSS-Tricks. You know, where in a line like
<div> part is a different color than the
test part. This is very helpful for code readability. It also helps readers instantly understand what they are looking at is a code block (people like to scan articles, don’t you know).
It takes us a minute to understand that there isn’t anything you “call”, it just kinda works assuming you have the correct class names in place. We finish up by playing around with the CSS a little bit and making the code look more like it always has on CSS-Tricks.
