<h1>Change scroll-padding-block property with JavaScript</h1>

<p>Try first to scroll to see how the child elements snap into place on start of the container in block direction.</p>

<p>Now, click button, click inside the container, and see how scrolling behaviour has changed. The elements still snap into place on start of the container like before, but now with a 20px distance in block direction from the start of the container to the child elements.</p>
