The Twenty Thirteen theme uses something called “Masonry” to realign footer widgets when you resize the browser window. What is Masonry? Who made it? And… well, actually these questions are irrelevant.

The fact is that Masonry is now part of the WordPress core download, and it can be activated and used in WordPress themes and plugins with just a few lines of code and some clear theme organization. I will walk theme and plugin developers through how to activate Masonry, how to make it work on a front page layout, and how to activate dazzling animation options included in the script.
