I don’t want to manually set all the syntax coloring for various blocks that I will want to include on my site.
Bingoogling resulted in a few hits.
Google Prettify comes up quickly, as does SyntaxHighlighter, and Highlighter.js.
This page had good information: https://codegeekz.com/15-code-syntax-highlighters-to-prettify-your-code/
I think I like Highlighter.js the most, so I’ll add it now.
