In the last post, I switched to a new syntax highlighter for WordPress that I’d like to recommend to the rest of the word, namely the Crayon Syntax highlighter available on the wordpress plugin site: Crayon
It’s got a huge set of features, a wide range of styles, installs and runs perfectly and even had backwards comparability to my old mini tags.
Hope you too like it better than the old one.
Update 2019-07-29:
I’ve since moved on to the Enlighter plugin which also works nicely with Gutenberg.
