CSS pseudo-class: not (: first-child) on the tbody element

June 16, 2022

I’m trying to style all tbody tags except the first one but with poor results.

As you can see in the snippet, the style is applied to all elements, including the first one, where am I wrong?

div.cont_table_toggle table#general_list tbody.divider:not(:first-child) {
  border-top: 8px solid red;
}

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet"/>

<div class="cont_table_toggle">
  <table id="general_list" class="table table-bordered">
    <thead>
      <tr>
        <th>AAAA</th>
        <th>BBBB</th>
      </tr>
    </thead>
    <tbody id="block-1" class="divider">
      <tr>
        <td>1111</td><td>2222</td>
      </tr>
    </tbody>
    <tbody id="block-2" class="divider">
      <tr>
        <td>3333</td><td>4444</td>
      </tr>
    </tbody>
    <tbody id="block-3" class="divider">
      <tr>
        <td>5555</td><td>6666</td>
      </tr>
    </tbody>
  </table>
</div>

>Solution :

Try using tbody.divider:not(:first-of-type).

The :first-of-type selector matches every element that is the first child, of a particular type, of its parent.

Try it below.

div.cont_table_toggle table#general_list tbody.divider:not(:first-of-type) {
  border-top: 8px solid red;
}

<div class="cont_table_toggle">
  <table id="general_list" class="table table-bordered">
    <thead>
      <tr>
        <th>AAAA</th>
        <th>BBBB</th>
      </tr>
    </thead>
    <tbody id="block-1" class="divider">
      <tr>
        <td>1111</td><td>2222</td>
      </tr>
    </tbody>
    <tbody id="block-2" class="divider">
      <tr>
        <td>3333</td><td>4444</td>
      </tr>
    </tbody>
    <tbody id="block-3" class="divider">
      <tr>
        <td>5555</td><td>6666</td>
      </tr>
    </tbody>
  </table>
</div>
