CSS transforms are a powerful feature that allow you to modify the appearance and position of elements on your web page. They provide a way to scale, rotate, translate, and skew elements without affecting the layout of surrounding content.

Basic Syntax

The transform property is used to apply transformations. It can take one or more transformation functions as its value.

selector {
    transform: function(value);
}

Common Transform Functions

1. Scale

The scale() function changes the size of an element.

.scale-example {
    transform: scale(1.5); /* Scales the element to 150% of its original size */
}

2. Rotate

rotate() turns an element around a fixed point.

.rotate-example {
    transform: rotate(45deg); /* Rotates the element 45 degrees clockwise */
}

3. Translate

Use translate() to move an element from its current position.

.translate-example {
    transform: translate(50px, 100px); /* Moves the element 50px right and 100px down */
}

4. Skew

The skew() function tilts an element along its axes.

.skew-example {
    transform: skew(10deg, 20deg); /* Skews the element 10 degrees horizontally and 20 degrees vertically */
}

Combining Transforms

Multiple transform functions can be combined in a single transform property. The order of application matters.

.combined-example {
    transform: rotate(45deg) scale(1.5) translate(50px, 50px);
}

3D Transforms

CSS also supports 3D transformations. These include rotateX(), rotateY(), rotateZ(), and translate3d().

Transform Origin

The transform-origin property sets the point around which a transformation is applied. By default, it's the center of the element.

.origin-example {
    transform-origin: top left;
    transform: rotate(45deg);
}

Best Practices

Use transforms for visual enhancements, not for layout purposes.
Combine transforms with CSS Transitions for smooth animations.
Be mindful of performance, especially with 3D transforms on mobile devices.
Test across different browsers to ensure consistent behavior.

Browser Support

CSS transforms are widely supported in modern browsers. However, for older browsers, you may need to use vendor prefixes or consider fallback options.
