Can I define a class name on paragraph using Markdown?

Question

Can I define a class name on paragraph using Markdown? If so, how?

Answer 1

Markdown should have this capability, but it doesn't. Instead, you're stuck with language-specific Markdown supersets:

PHP: Markdown Extra
Ruby: Kramdown, Maruku

But if you need to abide by true Markdown syntax, you're stuck with inserting raw HTML, which is less ideal.
