CSS Shorthand Properties

A simple way to list all shorthand CSS properties and which properties they expand to.

I tried to search for an existing simple list but couldn’t find one, so I trawled through the various W3C CSS specs and collated the data.

Only specs that are Candidate Recommendations or better are counted, with the exception of some Working Drafts that have a lot of traction in browser implementations. So far the WD specs included here are Animation and Transitions.

Usage

Available on npm as css-shorthand-properties, or in the browser as a global called cssShorthandProps

Properties

shorthandProperties

The core data as a simple JS object. Each key is a CSS shorthand property. Each value is a compacted list of CSS properties that the shorthand expands to.

There is a convenience method (listed below) that means you shouldn’t need to access this list directly, but it’s available for other use cases.

Methods

isShorthand

Returns a boolean indicating if a CSS property is a shorthand.
Parameters:
- property (String) Shorthand property to expand.
Returns: Boolean

cssShorthandProps.isShorthand('border');  // true
cssShorthandProps.isShorthand('display');  // false

expand

Takes a CSS shorthand property and returns a list of longhand properties.
Parameters:
- property (String) Shorthand property to expand.
- recurse (Boolean – optional, default false) If true, each longhand property will also be run through expand(). This is only useful for the border property.
Returns: Array with a list of longhand properties that the given property expands to. If the property is not a shorthand, the array contains only the original property.

// Standard usage
cssShorthandProps.expand('list-style');
// ['list-style-type', 'list-style-position', 'list-style-image']

// Non-shorthand properties return themselves in an array
cssShorthandProps.expand('color');
// ['color']

// Using 'border' in normal mode...
cssShorthandProps.expand('border');
// ['border-width', 'border-style', 'border-color']

// ...but the border properties are also shorthands
cssShorthandProps.expand('border-width');
// ['border-top-width', 'border-right-width', 'border-bottom-width', 'border-left-width']

// Using 'border' with recursion returns an array of arrays
cssShorthandProps.expand('border', true);
/*
[
  ['border-top-width', 'border-right-width', 'border-bottom-width', 'border-left-width'],
  ['border-top-style', 'border-right-style', 'border-bottom-style', 'border-left-style'],
  ['border-top-color', 'border-right-color', 'border-bottom-color', 'border-left-color']
]
