Simplifying CSS Transforms with Individual Properties

The Challenges of the Transform Property

For years, CSS transforms have been a fundamental aspect of web development, allowing us to create complex animations and interactions. However, working with the transform property can be cumbersome, especially when dealing with multiple values.

Two key challenges arise when working with this property:

• Use it or lose it: When defining multiple transform functions, each function must be declared in every state, or its value will be lost. This leads to duplicated code and makes maintenance more complicated.
• Order of operations: The order in which transform functions are applied matters. This can result in unexpected behavior if not managed correctly.

Introducing Individual Transform Properties

To overcome the limitations of the transform property, CSS has introduced three new individual transform properties:

• rotate: Controls rotation
• scale: Handles scaling
• translate: Manages translation

These properties work independently, eliminating the need to duplicate values across states. They also follow a more predictable sequence: translate, rotate, scale.

.element {
  translate: 100px 200px;
  rotate: 45deg;
  scale: 1.5;
}

Benefits and Considerations

Individual transform properties offer several benefits, including:

• Simplified code and reduced duplication
• Easier management of complex animations
• Improved performance, as only changed values are updated

However, there are some considerations to keep in mind:

• Transform-origin: Still used to define the origin point for transformations, but now works with individual properties
• Setting values to 0: Requires a unit or CSS keyword for individual properties, unlike the transform property
• Will-change property: Can still be used to optimize performance, but should be applied judiciously

Support and Fallbacks

Modern browsers already support individual transform properties, but for older browsers, fallbacks can be implemented using the @supports query. To streamline this process, an SCSS mixin can be used to automate the creation of fallbacks.

@mixin transform-fallback {
  @supports (translate: 100px 200px) {
    translate: 100px 200px;
  } else {
    transform: translate(100px, 200px);
  }
}
