Transforms

CSS transforms apply 2D transformations to elements — translation, rotation, scaling, and skewing.

Basic Usage

.box {
  transform: rotate(45deg);
}

Transform Functions

Translate

Move an element from its position:

.box { transform: translateX(20px); }
.box { transform: translateY(-10px); }
.box { transform: translate(20px, -10px); }

Percentage values reference the element's own size:

.box { transform: translateX(50%); }

Rotate

Rotate an element around its origin:

.box { transform: rotate(45deg); }
.box { transform: rotate(-90deg); }

Scale

Resize an element:

.box { transform: scale(1.5); }
.box { transform: scale(0.8); }
.box { transform: scaleX(2); }
.box { transform: scaleY(0.5); }

Skew

Tilt an element:

.box { transform: skewX(10deg); }
.box { transform: skewY(-5deg); }
.box { transform: skew(10deg, -5deg); }

Chaining Transforms

Apply multiple transforms by space-separating them:

.box {
  transform: translateX(20px) rotate(45deg) scale(1.2);
}

Transforms are applied right-to-left: first scale, then rotate, then translate.

Transform Origin

Set the point around which transforms occur:

.box {
  transform-origin: center center;
  transform-origin: top left;
  transform-origin: 50% 50%;
}

Default is 50% 50% (center of the element).

Tailwind Utilities

<div className="translate-x-4">Moved right 16px</div>
<div className="-translate-y-2">Moved up 8px</div>
<div className="rotate-45">Rotated 45deg</div>
<div className="-rotate-90">Rotated -90deg</div>
<div className="scale-110">Scaled up 10%</div>
<div className="scale-95">Scaled down 5%</div>
<div className="skew-x-6">Skewed</div>
<div className="rotate-[30deg]">Arbitrary rotation</div>
<div className="scale-[1.3]">Arbitrary scale</div>

Transitions with Transforms

Transforms animate smoothly with CSS transitions:

.box {
  transition: transform 0.3s ease;
}

.box:hover {
  transform: translateY(-4px) scale(1.02);
}

How It Works

Morph parses transform functions into an internal representation, composes them into a 4x4 matrix (mat4), and applies the result in the vertex shader. This means transforms are GPU-accelerated and don't affect layout.

The MORPH_FEATURE_TRANSFORM compile-time gate ensures transform code is only included when a transform property is detected in your app.
