Values | Sass supports a number of value types, most of which come straight from CSS. Every [expression](/documentation/syntax/structure#expressions) produces a value, [variables](/documentation/variables) hold values. Most value types come straight from CSS: |
-
Numbers, which may or may not have units, like
12
or100px
. -
Strings, which may or may not have quotes, like
"Helvetica Neue"
orbold
. -
Colors, which can be referred to by their hex representation or by name, like
#c6538c
orblue
, or returned from functions, likergb(107, 113, 127)
orhsl(210, 100%, 20%)
. -
Lists of values, which may be separated by spaces or commas and which may be enclosed in square brackets or no brackets at all, like
1.5em 1em 0 2em
,Helvetica, Arial, sans-serif
, or[col1-start]
.
A few more are specific to Sass:
-
The boolean values
true
andfalse
. -
The singleton
null
value. -
Maps that associate values with keys, like
("background": red, "foreground": pink)
. -
Function references returned by
get-function()
and called withcall()
.
