Highlight.js highlights syntax in code examples on blogs, forums and in fact on any web pages. It’s very easy to use because it works automatically: finds blocks of code, detects a language, highlights it. Learn more.
You can even use Github Flavored Markdown
We also use the scrivo/highlight.php package to highlight on rendering when possible. Highlight.js is a powerful but heavy library, since we don’t know which languages you’ll use we included all of them.
The good news is; if you use a fenced code block (```
) with the language defined, the rendering is done on server side and entirely skips loading Highlight.js on the page. While still having the same end-result on your code.
