Foundation Overlay is a Chrome extension developed by Daniel Samuels. It falls under the category of Browsers, specifically Add-ons & Tools. This free extension is designed to create an overlay for the Foundation grid system.

With Foundation Overlay, you can easily display the grid overlay on top of your website built on the Foundation framework. The extension detects custom grid widths, as long as Foundation is using the default container and span classes. This feature allows you to visualize and align your content according to the grid system, ensuring a consistent layout.

Foundation Overlay is a forked project from the popular Bootstrap overlay extension. It provides a similar functionality but tailored specifically for the Foundation framework. If you are a web developer or designer working with Foundation, this extension can be a valuable tool in your workflow.
