Riley Wave Stripes

A banner of tight black and white stripes. On hover a sine wave travels across: every stripe shifts, widens and bends by its own phase, so the flat surface seems to ripple in depth.

Also known as: op art stripes css, bridget riley hover, wavy stripes animation, optical illusion banner.

Customizing this snippet

  • Color: set --hfx-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --hfx-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.
