The theme team just released a brand new responsive-ready child theme for iThemes Builder, Avail. With a clean, modern design, Avail is great for business or corporate websites:
Paired with iThemes Builder 4.0, Avail automatically responds for mobile, tablet and desktop viewing. Check out Avail’s demo site to see it in action.
All Builder Developer Pack, All Access Theme Pass and Toolkit members will find Avail available as a new download in their iThemes Member Panel. Avail is also available stand-alone.
