The counter-set
CSS property sets a CSS counter to a given value. It manipulates the value of existing counters, and will only create new counters if there isn't already a counter of the given name on the element.
The counter-set
CSS property sets a CSS counter to a given value. It manipulates the value of existing counters, and will only create new counters if there isn't already a counter of the given name on the element.
Note: The counter's value can be incremented or decremented using the counter-increment
CSS property.
/* Set "my-counter" to 0 */ counter-set: my-counter; /* Set "my-counter" to -1 */ counter-set: my-counter -1; /* Set "counter1" to 1, and "counter2" to 4 */ counter-set: counter1 1 counter2 4; /* Cancel any counter that could have been set in less specific rules */ counter-set: none; /* Global values */ counter-set: inherit; counter-set: initial; counter-set: revert; counter-set: revert-layer; counter-set: unset;
The counter-set
property is specified as either one of the following:
<custom-ident>
naming the counter, followed optionally by an <integer>
. You may specify as many counters to reset as you want, with each name or name-number pair separated by a space.none
.<custom-ident>
The name of the counter to set.
<integer>
The value to set the counter to on each occurrence of the element. Defaults to 0
if not specified. If there isn't currently a counter of the given name on the element, the element will create a new counter of the given name with a starting value of 0 (though it may then immediately set or increment that value to something different).
none
No counter set is to be performed. This can be used to override a counter-set
defined in a less specific rule.
