The symbols
CSS descriptor is used to specify the symbols that the specified counter system will use to construct counter representations. A symbol can be a string, image, or identifier. It is used within the @counter-style
at-rule.
symbols: A B C D E; symbols: "\24B6" "\24B7" "\24B8" D E; symbols: "0" "1" "2" "4" "5" "6" "7" "8" "9"; symbols: url('first.svg') url('second.svg') url('third.svg'); symbols: indic-numbers;
The symbols
descriptor must be specified when the value of the system
descriptor is cyclic
, numeric
, alphabetic
, symbolic
, or fixed
. When the additive
system is used, use the additive-symbols
descriptor instead to specify the symbols.
