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:

|---|---|
| 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!" |
