How to increment Counter in CSS for a list with :before-CodePudding

I tried to increment a counter for a list with CSS.

However, even though I can see the list numbers, those don't increment.

I used :before and the CSS property counter.

.services__details--content__step > ul > li:before {
  content: counter(counter);
  counter-increment: counter;
  color: #0052ff;
  background-color: #e8effe;
  display: inline-flex;
  width: 40px;
  height: 40px;
  align-items: center;
  justify-content: center;
  margin-right: 16px;
  border-radius: 50%;
}

The HTML code is as follows:

<div >
              <h2 >
                Les Étapes de la Création du Site
              </h2>
              <ul>
                <li>
                  Évaluation du Projet
                  <p >

                    typesetting industry. Lorem Ipsum has been the
                    industry’s standard dummy text ever since the 1500s,
                    when an unknown printer.

              </ul>
            </div>

You need to set the counter to 0 first.
The only thing you need to do is add:

body {
  /* Set "counter" to 0 */
  counter-reset: counter;
}

.services__details--content__step > ul > li:before {
  content: counter(counter);
  counter-increment: counter;
  color: #0052ff;
  background-color: #e8effe;
  display: inline-flex;
  width: 40px;
  height: 40px;
  align-items: center;
  justify-content: center;
  margin-right: 16px;
  border-radius: 50%;
}

body {
  /* Set "counter" to 0 */
  counter-reset: counter;
}

<div >

You need counter-reset.

body {
   counter-reset: counter;
}
