Cut Corners using CSS

Cutting the clutter: Enhancements and alternatives

Taking advantage of CSS pseudo-elements

Want your cut to stay away from your content? Pseudo-elements are here for the rescue!

.cut-corners:before {
  content: '';
  position: absolute;
  top: 0;
  right: 0;
  /* Bob the Builder, can we fix it? Yes we 'border-can'! */
  border-left: 20px solid white;
  border-bottom: 20px solid transparent;
}


Remember, border sizes influence the cut size, so play with them till it fits just right. Also, keep the z-index in mind, so your layers interact correctly and your design doesn't fall flat.

border-corner-shape: The future of cut corners

The upcoming CSS property, border-corner-shape, promises to cut those corners without breaking a sweat. It's not here yet, but the buzz is real and it's all very exciting.

Gradients and background color

Visual design matters, so make sure the background of your cut corners contrasts well.

.cut-corners {
  /* Gradually winning, my friend */
  background: linear-gradient(135deg, #4CAF50 50%, white 50%);
}


The gradient's angles and color transitions can be adjusted for the perfect cut effect.

Responsive design and compatibility

Want those cut corners to look great on all devices? Turn to responsive percentages or CSS variables for assistance. Don't forget to check browser support on Can I Use and add vendor prefixes if needed.

Experimentation: Creating a folded corner look

Dealing a skewed hand

For another cut corner look, try deviating with the skew CSS transform property:

.cut-corners::before {
  content: '';
  position: absolute;
  /* Do the twist! */
  transform: skew(-15deg);
}


Playing around with skew angles can yield exceptional results, but be careful, it might mess with your border rendering. Using transform-origin lets you control the pivot point of the skew.

Interactivity: Code examples and tools

It's easier to see the effects in real-time. Use jsfiddle or CodePen to experiment with your code before committing to it. Tools like Clippy offer an intuitive way to generate custom shapes for clip-path without having to decode the mathematics.
