CSS Snippets

Pure CSS Hover Effects

A collection of reusable, dependency-free hover effects built with plain CSS transitions and transforms. Hover any preview to see the effect live, then copy the exact stylesheet that drives it.

Underline Slide

A single underline slides in from the right while the label tints toward the accent color.

CSS
/* Underline slide */
.ddk-hover-underline {
  position: relative;
  display: inline-flex;

.ddk-hover-underline:hover {
  color: #C4B5FD;
}
.ddk-hover-underline:hover::after {
  transform: scaleX(1);
  transform-origin: left center;
}

Lift + Shadow

The element floats upward and casts a soft, accent-tinted shadow beneath it.

Hover me
CSS
/* Lift + shadow */
.ddk-hover-lift {
  display: inline-flex;
  align-items: center;
  justify-content: center;
  padding: 12px 22px;
  font-size: 0.9rem;
  font-weight: 600;

  border: 1px solid rgba(255, 255, 255, 0.14);
  border-radius: 8px;
  cursor: pointer;
  user-select: none;
  box-shadow: 0 1px 2px rgba(0, 0, 0, 0.5);
  transition: transform 0.3s ease, box-shadow 0.3s ease, border-color 0.3s ease;
}
.ddk-hover-lift:hover {
  transform: translateY(-6px);
  border-color: rgba(163, 95, 255, 0.6);
  box-shadow: 0 14px 30px -8px rgba(163, 95, 255, 0.45);
}

Scale

Grows slightly with a tactile zoom and a deeper accent glow around the edges.

Hover me
CSS
/* Scale */
.ddk-hover-scale {
  display: inline-flex;
  align-items: center;
  justify-content: center;
  padding: 12px 22px;

  transform: scale(1.08);
  box-shadow: 0 8px 24px -6px rgba(163, 95, 255, 0.65);
}

Border Glow

The border ignites into an accent outline with a soft outer halo, like a neon edge.

Hover me
CSS
/* Border glow */
.ddk-hover-glow {
  display: inline-flex;
  align-items: center;
  justify-content: center;
  padding: 12px 22px;

  font-weight: 600;
  line-height: 1;
  color: #E4E4E7;
  background: #27272A;
  border: 1px solid rgba(255, 255, 255, 0.14);
  border-radius: 8px;
  cursor: pointer;
  user-select: none;
  transition: border-color 0.3s ease, box-shadow 0.3s ease;
}
.ddk-hover-glow:hover {
  border-color: #A35FFF;
  box-shadow: 0 0 0 1px #A35FFF, 0 0 24px rgba(163, 95, 255, 0.55);
}

Gradient Sweep

A purple gradient sweeps across the background while the label brightens to white.

Hover me
CSS
/* Gradient sweep */
.ddk-hover-sweep {
  position: relative;
  z-index: 0;
  display: inline-flex;

  inset: 0;
  z-index: -1;
  background: linear-gradient(120deg, #A35FFF 0%, #7C3AED 100%);
  transform: translateX(-101%);
  transition: transform 0.4s ease;
}
.ddk-hover-sweep:hover {
  color: #FFFFFF;
}
.ddk-hover-sweep:hover::before {
  transform: translateX(0);
}

Shrink

  transform: scale(0.92);
  box-shadow: 0 1px 4px -2px rgba(163, 95, 255, 0.4);

Rotate

Tilts and scales with a subtle overshoot for a playful, springy nudge.
