counter-set
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.
Try it
Note: The counter's value can be incremented or decremented using the counter-increment
CSS property.

counter-set: my-counter -1;
/* Set "counter1" to 1, and "counter2" to 4 */
counter-set: counter1 1 counter2 4;

The counter-set

- A
<custom-ident>

. You may specify as many counters to reset as you want, with each name or name-number pair separated by a space. - The keyword value
none
.
Values
<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.
