slimScroll is a small (2.8KB) jQuery plugin that transforms any div into a scrollable area with a nice scrollbar – similar to the one Facebook and Google started using in their products recently. slimScroll doesn’t occupy any visual space as it only appears on a user initiated mouse-over. User can drag the scrollbar or use mouse-wheel to change the scroll value.
jQuery Picture is a tiny (2kb) plugin to add support for responsive images to your layouts. It supports both figure elements with some custom data attributes and the new proposed picture format. This plugin will be made redundant when the format is approved and implemented by browsers. Lets hope that happens soon but in the meantime this plugin will be kept up to date with latest developments.
