Lays.js

Tiny cascading grid layout library. Masonry - great library, but has unnecessary code, quite heavy and doesn't have items limit (for example, to show fresh 10 items only). These are the main reasons that led to write a Lays.js.

• Size -> Tiny size (< 2kb)!!
• Dynamic -> Dynamically add new items.
• No dependencies -> No jQuery!
• Browsers support -> IE 9+.
