Video full screen button

The full screen button causes the viewer to enter or exit full screen mode when clicked by the user. It is used when the viewer is displaying video and is located in the control bar. This button is not displayed if the viewer works in pop-up mode and the system does not support native full screen.
You can size, skin, and position the full screen button, relative to the control bar that contains it, by CSS.
The appearance of the full screen button is controlled with the CSS class selector:
.s7mixedmediaviewer .s7fullscreenbutton

CSS properties of the full screen button
top
Position from the top border, including padding.
right
Position from the right border, including padding.
left
Position from the left border, including padding.
bottom
Position from the bottom border, including padding.
width
The width of the full screen button.
height
The height of the full screen button.
background-image

This button supports both the state and selected attribute selectors, which can be used to apply different skins to different button states. In particular, selected='true' corresponds to the "full screen" state and selected='false' corresponds to the "normal" state.
The button tool tip can be localized. See Localization of user interface elements for more information.

Example
