Frequently asked questions
Which languages are supported?
Highlighting covers the wide set of languages bundled with highlight.js; add the language after the opening code fence (for example ```python).
Does highlighting affect my Markdown?
No. Coloring is visual only; your Markdown source is unchanged.
Is the highlighter downloaded up front?
No — it loads only when you open this tool, keeping the rest of the site fast.
