The rule

When content is too long for one screen, a scrollbar is needed.

The footer should appear only when the user scrolls to the bottom. Up and down arrows should be fixed in the bottom-right corner.

A page with much content needs a scrollbar. The footer should not always be visible. It should appear when the user reaches the bottom of the page. This saves screen space. Small up and down arrows should stay in the bottom-right corner. These arrows help the user move through the page. They also show if more content is available. The up arrow dims at the top of the page. The down arrow dims at the bottom of the page.

A developer creates a long article page. The developer hides the footer until the user scrolls to the end. The developer adds small up and down arrows to the bottom-right. This helps users navigate the long text. It also tells them when they are at the top or bottom.
