:fullscreen CSS Pseudo Class

Description

The :fullscreen pseudo-class applies to elements when the browser is in full-screen mode. At the same time, the window title, address bar, tabs, menus and other standard elements are hidden and the browser is displayed in full screen. To switch from standard mode to full screen and vice versa, the F11 key is usually used.
