of Kevin Lindsey's SVG geometry library, modified slightly to support elliptical arcs, for finding collisions. My original plan was to use the browser checkIntersection() built-in but it didn't work properly in any browsers.

Slidebars is a jQuery framework for creating app-style off-canvas menus and sidebars.

Born in 2014 from a reoccurring need to create mobile menus in responsive design, Slidebars has quickly become the number one choice for developers. With the release of version 2, Slidebars packs more functionality than ever before with an even lighter footprint.

Weighing in at only 1.69kb gzipped, the new Slidebars features clean and discreet markup, permits an unlimited number of off-canvas instances on any side and is equipped with a full API, callbacks and events for ultimate control.
