How this works

Every wipe places a ::before element that covers the full button and transitions its transform or clip-path from hidden to revealed. The left wipe uses transform: scaleX(0); transform-origin: left — on hover it scales to scaleX(1), dragging the fill color across the face of the button. The center-split starts with two clip-path: inset(0 50% 0 0) halves that wipe toward their outer edges simultaneously.

The diagonal slash uses a skewX(-25deg) on a scaleX(0) pseudo with transform-origin: left — the skew tilts the leading edge into a diagonal slash while scaleX sweeps it across the button. Clipped by the button's overflow: hidden, the result is a clean angled wipe with no overhang at rest. The radial burst variant uses a border-radius: 50% pseudo scaled from scale(0) to scale(3), expanding from center outward and clipped to the button rectangle.

Make it yours

  • Match the fill color to the hover text color — when the wipe is dark, ensure the :hover ruleset flips color to a light value.
  • Chain the fill with a border-radius transition to morph the button shape as it fills — border-radius: 0 on hover flattens a rounded pill into a rectangle.
  • Use a gradient instead of a solid fill on ::before — background: linear-gradient(135deg, var(--a), var(--b)) adds visual richness to the wipe.
  • Add will-change: transform to the ::before only when the button is within :focus-within to pre-promote the layer without wasting GPU memory.
  • Pair with a matching transform: scale(1.03) on the button itself for a combined hover lift + fill effect.

Gotchas — read before shipping

  • The wipe fill sits behind the button label — always set z-index: 0 on ::before and position: relative; z-index: 1 on the text content.
  • Diagonal wipes require overflow: hidden on the button — removing it causes the rotated ::before to bleed outside the button bounds visibly.
  • transform: scaleX(0) collapses the fill to zero but keeps the element in flow; using width: 0 instead can cause subpixel rendering gaps on retina displays.
