A default plugin of Expressive Code, an engine for presenting source code on the web.
It allows you to mark entire lines & line ranges, as well as individual text inside your lines using a selection of marker styles (marked, inserted, deleted).
It also ensures accessible color contrast of the marked code, automatically tweaking the text colors if necessary while keeping syntax highlighting intact.
Read this plugin's documentation on the Expressive Code website to learn more about its features.
