Meaning:
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.

Property Values
The following table describes the values of this property:
Value | Description |
---|---|
id | 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. |
initial | Sets this property to its default value. |
inherit | If specified, the associated element takes the computed value of its parent element animation-delay property. |
revert | Reverts the cascaded value of the property from its current value to the value the property |
revert-layer | Rollback styles to the ones specified in previous cascade layers. |
unset | Resets a property to its inherited value if the property naturally inherits from its parent, and to its initial value if not. |
