<h1>Change scroll-margin-left property with JavaScript</h1>

<p>Try first to scroll to see how the scroll snaps on start of elements on x-axis.</p>

<p>Now, click button, click inside the container, and see how scrolling behaviour has changed. The elements now snap on start of element, but with a 20px margin to container on the left side.</p>
