Sass String Functions

Sass String Functions

The string functions are used to manipulate and get information about strings.

Sass strings are 1-based. The first character in a string is at index 1, not 0.

The following table lists all string functions in Sass:

Function	Description & Example
quote(string)	Adds quotes to string, and returns the result. Example: quote(Hello world!) Result: “Hello world!”
str-index(string, substring)	Returns the index of the first occurrence of the substring within string. Example: str-index(“Hello world!”, “H”) Result: 1
str-insert(string, insert, index)	Returns string with insert inserted at the specified index position. Example: str-insert(“Hello world!”, ” wonderful”, 6) Result: “Hello wonderful world!”
str-length(string)	Returns the length of string (in characters). Example: str-length(“Hello world!”) Result: 12
str-slice(string, start, end)	Extracts characters from string; start at start and end at end, and returns the slice. Example: str-slice(“Hello world!”, 2, 5) Result: “ello”
to-lower-case(string)	Returns a copy of string converted to lower case. Example: to-lower-case(“Hello World!”) Result: “hello world!”
to-upper-case(string)	Returns a copy of string converted to upper case. Example: to-upper-case(“Hello World!”) Result: “HELLO WORLD!”
unique-id()	Returns a unique randomly generated unquoted string (guaranteed to be unique within the current sass session). Example: unique-id() Result: tyghefnsv
