Foundation was designed for and tested on numerous browsers and devices. Here's the rundown on what's tested, and what to do if something misbehaves.
Browser and Device Support
We go to great lengths to ensure that Foundation works as expected on a variety of common browsers and devices. Given how forward-facing Foundation is there are some aesthetic properties which are not supported in older browsers (border radii, box shadows, etc), but the core elements are reliable across the board.
