Aether is an HTML5 responsive starter theme built with Sass & Compass using a grid system that is configurable via theme-settings & through Sass variables. Taking the fixed-width responsive approach, it has 5 device widths, 4 breakpoints and uses the widest width as the default.
Aether offers variables and mixins to make initial project setup and implementation fast and flexible.
