How to remove sub number in my ordered List?

Question

I have problem with css styling of my Ordered List.

I have my HTML code:

ol {
  counter-reset: item
}

li {
  display: block
}

li:before {
  content: counters(item, ".")" ";
  counter-increment: item
}

<ol>
  <li class="sub">one</li>
  <li class="">two
    <ol>
      <li class="small">two.one</li>
      <li class="small">two.two</li>
      <li class="small">two.three</li>
    </ol>
  </li>
  <li>three
    <ol>
      <li>three.one</li>
      <li>three.two
        <ol>
          <li>three.two.one</li>
          <li>three.two.two</li>
        </ol>
      </li>
    </ol>
  </li>
  <li>four</li>
</ol>

And I need to hide number value from 1 one, 2 two, 3 three and 4 four Someone has idea, how to do that, please?

Answer 1

You can mimick the behavior you are looking for by setting the font-size to 0px and this would make the element be counted by the counter property while hiding it.

.hide { 
    font-size: 0px;
}

<ol>
    <li>one</li>
    <li>two
        <ol>
            <li>two.one</li>
            <li class="hide">two.two</li>
            <li>two.three</li>
        </ol>
    </li>
    <li>three
        <ol>
            <li>three.one</li>
            <li>three.two
                <ol>
                    <li>three.two.one</li>
                    <li>three.two.two</li>
                </ol>
            </li>
            <li class="hide">three.three</li>
            <li>three.four</li>
        </ol>
    </li>
    <li>four</li>
</ol>
