Here is a gift from me to you. This is awesome. You know I’ve seen this on a limited number of blogs so I decided to do a little searching for this and voila! I found this theme tag on forum post linked from Tumblr. I made a little example above to share in context.
This also irritates me, because Tumblr is so piss poor to providing a complete documentation for their theme tags. They just recently cleaned it up a bit, but I could see if there was some guy new to coding for Tumblr looked at that library, they would be a little irked at the lack of description and examples a lot of the tags have.
Just sayin’. Please hire someone dedicated to properly maintaining the docs.Source: groups.google.com
