The counter-increment property increases or decreases the value of one or more CSS counters. The counter-increment property is usually used together with the counter-reset property and the content property.
Example :
body {
/* Set “my-sec-counter” to 0 */
counter-reset: my-sec-counter;
}
h2:before {
/* Increment “my-sec-counter” by 1 */
counter-increment: my-sec-counter;
content: “Section ” counter(my-sec-counter) “. “;
}
