-            <p>Similar to how light/dark mode behaviours are controlled with a toggle switch, commonly used with javascript for persistence of user's preference either to localStorage or a cookie on page reload.</p>

+            <p>The Open Props <a href="https://codepen.io/argyleink/pen/KKvRORE">normalize.css</a> has light and dark built in, but it only changes with the media query / operating system. If you want users to be able to change this, you'll need <b>Open Props switch imports</b>. These have the same theme values from normalize, but scoped to selectors.</p>
+
+            <p><b>Light Selectors:</b> <code>.light</code> | <code>.light-theme</code> | <code>data-theme="light"</code></p>
+            <p><b>Dark Selectors:</b> <code>.dark</code> | <code>.dark-theme</code> | <code>data-theme="dark"</code></p>
+
+            <p>This allows you to apply a light or dark theme to the page or a portion of the page using the selectors imported.</p>
