(both for semantics and for Prism) is a element with a element inside, like so: p The recommended way to mark up a code block Therefore, it only works with elements, since marking up code without a element is semantically invalid.Īccording to the HTML5 spec, the recommended way to define a code language is a language-xxxx class, which is what Prism uses.Īlternatively, Prism also supports a shorter version: lang-xxxx. Prism does its best to encourage good authoring practices. You will need to include the prism.css and prism.js files you downloaded in your page. If someone can read code, they are probably in the 95% of the population with a modern browser. Some of our themes have problems with certain layouts.Regex-based so it *will* fail on certain edge cases, which are documented in the known failures page.Any pre-existing HTML in the code will be stripped off.Autolink URLs and emails, use Markdown links in comments (requires plugin).Show invisible characters like tabs, line breaks etc (requires plugin).Highlight specific lines and/or line ranges (requires plugin).So, you can just try it for a while, remove it if you don’t like it and leave no traces behind. It doesn’t force you to use any Prism-specific markup, not even a Prism-specific class name, only standard markup you should be using anyway.Highlights inline code as well, not just code blocks.CSS inside HTML, JavaScript inside HTML). Wide browser support: Edge, IE11, Firefox, Chrome, Safari, Opera, most mobile browsers.All styling is done through CSS, with sensible class names rather than ugly, namespaced, abbreviated nonsense.The only thing you need is a good understanding of regular expressions. Multiple hooks are scattered throughout the source. Very easy to extend without modifying the code, due to Prism’s plugin architecture.Supports parallelism with Web Workers, if available.This means that if multiple code snippets have the same language, you can just define it once,in one of their common ancestors. In addition, the language is defined through the way recommended in the HTML5 draft: through a language-xxxx class. On its own for inline code, or inside a for blocks of code. Prism forces you to use the correct element for marking up code. Other highlighters encourage or even force you to use elements that are semantically wrong, Each language definition adds roughly 300-500 bytes. If you’re still not sold, you can view more examples or try it out for yourself.
