Enlighter is a free, easy-to-use, syntax highlighting tool for WordPress. Highlighting is powered by the EnlighterJS javascript library to provide a beautiful code-appearance.

Using it can be as simple as adding a new Enlighter Sourcecode block (Gutenberg) and insert the code which you want to highlight: Enlighter takes care of the rest!

An easy to use Theme-Customizer is included to modify the build-in themes without any css knowlegde!
It also supports the automatic creation of tab-panes to display code-groups together (useful for multi-language examples – e.g. html+css+js)
