This feature request on MSO: Alternate (visually distinguishable) blockquote style
I'd like to see Bible quotes have a style of their own. They're very centric to the site, but we have a lot of other quotes, too. It would be great to be visually able to distinguish them.
A possible implementation would be to have a "hint" not unlike the syntax highlighting language hints used on SO. Something like
<!-- bible --> > [**John 1:1 (ESV)**](http://www.biblegateway.com/passage/?search=john%201:1&version=ESV) > <sup>1</sup> In the beginning was the Word, and the Word was with God, and the Word was God.
...and this would apply a CSS class that changes the background color of the blockquote.
