title: How to hover only the current li in nested ul?
body: <p>I have a nested list:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>li:hover {
    background-color: lightgray;
  }
  ul li ul li:hover {
    font-weight: bold;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;ul&gt;
    &lt;li&gt;fnord
      &lt;ul&gt;
        &lt;li&gt;baz&lt;/li&gt;
        &lt;li&gt;foo
          &lt;ul&gt;
            &lt;li&gt;baz&lt;/li&gt;
            &lt;li&gt;foo&lt;/li&gt;
          &lt;/ul&gt;
        &lt;/li&gt;
      &lt;/ul&gt;
    &lt;/li&gt;
    &lt;li&gt;gnarf
      &lt;ul&gt;
        &lt;li&gt;baz&lt;/li&gt;
        &lt;li&gt;foo
          &lt;ul&gt;
            &lt;li&gt;baz&lt;/li&gt;
            &lt;li&gt;yolo&lt;/li&gt;
          &lt;/ul&gt;
        &lt;/li&gt;
      &lt;/ul&gt;
    &lt;/li&gt;
  &lt;/ul&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Problem is, hovering "foo" will also hover "fnord" and all of its <code>li</code> elements. How do I hover only the <code>li</code> my mouse is actually hovering over?</p>
  
  <p>The nesting is variable and can, in theory, be endless.</p>
