I just added a snippet integrating the cool new service placehold.it. Check out their site and the video below for more info.
Grab the latest version of my HTML bundle on github (I’m eventually going to discontinue the download on my site when I get the time to update it) or use the “Update Bundle via Git” option in the mHTML menu (make sure you have a document open if the option is grayed out, TextMate is funny that way…).
Enjoy!
