Freetile is a plugin for jQuery that enables the organization of webpage content in an efficient, dynamic and responsive layout. It can be applied to a container element and it will attempt to arrange it's children in a layout that makes optimal use of screen space, by "packing" them in a tight arrangement.
Freetile is inspired by similar, existing efforts such as Masonry, vGrid and Wookmark. However, it differs from these solutions in some aspects:
It allows for any size of elements to be packed without using a fixed-size column grid, so you don't have to worry about specifying a column width appropriate to the size of your elements.
The algorithm that evaluates each possible insertion position is easily customizable, allowing for different preferences to be expressed, e.g. a preference to left- or right-alignment of elements, or proximity between certain elements.
