Glass Stacked Cards

Three frosted cards stacked like a deck, each layer thickening the blur behind the next. Hover and they fan out with a staggered spring so every card shows. Transforms only, so it stays smooth.

Also known as: glassmorphism card stack css, stacked cards hover effect, fan out cards css.

Customizing this snippet

  • Color: set --gls-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --gls-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • Speed: change the duration on the transition or animation shorthand. Staggered delays are relative, so they keep their rhythm.
  • Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
