<h2 class="text-lg font-medium">Outside event example</h2>

When you're creating floating UI patterns such as tooltips or modal dialogs, you often need to handle the events "outside" of the target dom.
Capsule supports this pattern with "on.outside[eventName]".

<div class="outside-example">click outside of this area.</div>

<pre class="js-source overflow-x-scroll lg:rounded-lg shadow-lg bg-gray-800 text-gray-100 p-5 mt-5 -mx-2">const { on } = component("outside-example");
