<li><code>position: relative</code> on the parent establishes a Cartesian positioning context for psuedo-elements.</li>
<li><code>::after</code> defines a pseudo element.</li>
<li><code>background-image: linear-gradient(...)</code> adds a linear gradient that fades from transparent to white (top to bottom).</li>
<li><code>position: absolute</code> takes the pseudo element out of the flow of the document and positions it in relation to the parent.</li>
<li><code>width: 300px</code> matches the size of the scrolling element (which is a child of the parent that has the pseudo element).</li>
<li><code>height: 25px</code> is the height of the fading gradient psuedo element, which should be kept relatively small.</li>
<li><code>bottom: 0</code> positions the pseudo element at the bottom of the parent.</li>
<li><code>height: 25px</code> is the height of the fading gradient psuedo-element, which should be kept relatively small.</li>
<li><code>bottom: 0</code> positions the pseudo-element at the bottom of the parent.</li>
<li><code>pointer-events: none</code> specifies that the psuedo-element cannot be a target of mouse events, allowing text behind it to still be selectable/interactive.</li>
