Genesis Sandbox is a starter theme created by Jonathan Perez and developed by Travis Smith. It’s meant to be a base for all of your custom theme development, whether it’s for a client, theme building, or personal sites.
The child theme is built off a mixture of the Genesis 2.0 style sheet, 1.9 style sheet, and a few edits and tweaks of my own. It comes with all the SaSS files, or you can edit the style sheet directly.
Genesis Sandbox was built as a way to speed up development for your projects and it’s completely FREE!
