New CSS corner-shape + Animation Explained in 7 Minutes
In this video, you’ll learn how to use the brand-new CSS corner-shape property to design corners that go far beyond simple rounded edges.
Most of the time, we rely on border-radius to control corners. But with corner-shape, you can actually control how corners are drawn, allowing you to create scoop, notch, bevel, squircle, and even mathematically controlled shapes using superellipse() — all in pure CSS.
We’ll start by understanding what corner-shape is, how it works, and how it’s different from border-radius. Then we’ll explore every available value and see how they affect corner geometry in real time.
By the end of the video, we’ll build a real UI example using pricing cards, sale tags, buttons, and an animated blinking star effect, all powered by corner-shape. No clip-path, no SVGs, and no complex hacks — just clean, modern CSS.
You’ll also learn:
✓ Why corner-shape only works with border-radius
✓ How multiple corner values work (-1, 0, 1, and infinity values)
✓ How superellipse() gives fine-grained control over curves
✓ How to animate corners for creative UI effects
✓ Current browser support and limitations
This video is perfect for frontend developers and designers who want to experiment with modern CSS features and build more expressive, eye-catching interfaces.
