symbols()
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The symbols() CSS function enables defining counter styles inline, directly as a value of properties such as list-style, providing a less powerful but simpler alternative to the @counter-style method of defining a counter style.
Unlike @counter-style, which defines a reusable counter style, symbols() is anonymous (i.e., it can only be used once). This function accepts strings and images as values. In comparison, the @counter-style's symbols descriptor also accepts identifiers.
Syntax
css
symbols() = symbols( <symbols-type>? [ <string> | <image> ]+ );
<symbols-type> can be one of the following:
cyclic: The system cycles through the given values in the order of their definition, and returns to the start when it reaches the end.numeric: The system interprets the given values as the successive units of a place-value numbering system.alphabetic: The system interprets the given values as the digits of an alphabetic numbering system, like a place-value numbering system but without0.symbolic: The system cycles through the values, printing them an additional time at each cycle (one time for the first cycle, two times for the second, etc.).fixed: The system cycles through the given values once, then falls back to Arabic numerals.
