I’m working on a project for a client and they have a lot of rounded corners that really are essential to their branding. Implementing rounded corners, to a small degree, can be done easily with an image file, or can gracefully degrade to a squared corner in projects where the rounded corners aren’t essential. But for this client, there are a lot of rounded corners, and they are a MUST.
Luckily, Cameron Cooke and Mike Jolley put some hard work into creating a great jQuery solution: Curvey Corners.
With just a line of jQuery code, my rounded corners became round!
