Scroll to top

A button that appears after the reader scrolls down and takes them back to the top. Use it on long pages or long scrollable panels; without Selector it follows the window.

Inside a scrollable panel

Selector attaches the button to one scrolling element. The absolute class keeps it in the panel's corner instead of the window's.
