Description lists in Markdown
A lesser-known piece of Markdown syntax (and HTML) are description lists. Description lists are great for small bits of "key-value"-like information.
This is an title: This is a descriptionThis is another title: This is another descriptionDescription lists are great for lists where you want to write more than just a bullet, like my Reads page.
Description lists aren't part of the Markdown or CommonMark spec, but are widely supported (by the league/commonmark PHP package and iA Writer, which are the places I write most.)
