                <h3><code>:contains(text)</code> Selector</h3>
<div class="contains">
  <p>This is some random text inside a paragraph.</p>
  <p>I will be selecting all pararaphs that have the word "random".</p>
  <p>It is case sensitive. So, the capital RANDOM should not be selected.</p>
  <p>This weird rAndOM should not be selected either.</p>

<h3><code>:has(selector)</code> Selector</h3>
<div class="has">
  <p>This is some more random <b>text</b> inside a paragraph.</p>
  <p>This time I am supposed to find the <i>&lt;i&gt;</i> tag.</p>
  <p>It does not matter how <span><b><i>deeply</i></b></span> nested it is.</p>
  <p>As long as it is a descendant of <code>&lt;p&gt;</code>, it will be selected.</p>
