The counter-reset CSS property resets a CSS counter to a given value.
Note: The counter's value can be increased or decreased using the counter-increment CSS property.
/* Set "my-counter" to 0 */ counter-reset: my-counter; /* Set "my-counter" to -1 */ counter-reset: my-counter -1; /* Set "counter1" to 1, and "counter2" to 4 */ counter-reset: counter1 1 counter2 4; /* Cancel any reset that could have been set in less specific rules */ counter-reset: none; /* Global values */ counter-reset: inherit; counter-reset: initial; counter-reset: unset;
The counter-reset 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><integer>0 if not specified.nonecounter-reset defined in a less specific rule.[ <custom-ident> <integer>? ]+ | none
h1 {

/* Sets the chapter and page counters to 0,
and the section counter to 1 */
}
