In Sass, the map data type represents one or more key/value pairs
In Sass, the map data type represents one or more key/value pairs.
Sass maps are immutable (they cannot change). So, the map functions that return a map, will return a new map, and not change the original map.
The following table lists all map functions in Sass:
Function | Description & Example |
---|---|
map-get(map, key) | Returns the value for the specified key in the map. Example: $font-sizes: ("small": 12px, "normal": 18px, "large": 24px) map-get($font-sizes, "small") Result: 12px |
map-has-key(map, key) | Checks whether map has the specified key. Returns true or
false. Example: $font-sizes: ("small": 12px, "normal": 18px, "large": 24px) map-has-key($font-sizes, "big") Result: false |
map-keys(map) | Returns a list of all keys in map. Example: $font-sizes: ("small": 12px, "normal": 18px, "large": 24px) map-keys($font-sizes) Result: "small", "normal, "large" |
map-merge(map1, map2) | Appends map2 to the end of map1. Example: $font-sizes: ("small": 12px, "normal": 18px, "large": 24px) $font-sizes2: ("x-large": 30px, "xx-large": 36px) map-merge($font-sizes, $font-sizes2) Result: "small": 12px, "normal": 18px, "large": 24px, "x-large": 30px, "xx-large": 36px |
map-remove(map, keys...) | Removes the specified keys from map. Example: $font-sizes: ("small": 12px, "normal": 18px, "large": 24px) map-remove($font-sizes, "small") Result: ("normal": 18px, "large": 24px) map-remove($font-sizes, "small", "large") Result: ("normal": 18px) |
map-values(map) | Returns a list of all values in map. Example: $font-sizes: ("small": 12px, "normal": 18px, "large": 24px) map-values($font-sizes) Result: 12px, 18px, 24px |
