symbols() - CSS: Cascading Style Sheets 编辑

The symbols() CSS function lets you define counter styles inline, directly as the value of a property such as list-style. Unlike @counter-style, symbols() is anonymous (i.e., it can only be used once). Although less powerful, it is shorter and easier to write than @counter-style.

Syntax

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 without 0.
• 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.
