Properties

AvailHeight

The read-only Screen interface's
availHeight property returns the height, in CSS pixels, of
the space available for Web content on the screen. Since Screen is
exposed on the Window interface's Screen
property, you access availHeight using window.screen.availHeight.

[Value("availHeight")]
public long AvailHeight { get; }

Property Value

long

A numeric value indicating the number of CSS pixels tall the screen's available space
is. This can be no larger than the value of Height,
and will be less if the device or user agent reserves any
vertical space for itself.For instance, on a Mac whose Dock is located at the bottom of screen (which is the default), the value of availHeight is approximately the value of height (the total height of the screen in CSS pixels) minus the heights of the Dock and menu bar, as seen in the diagram below. They only take up availHeight if they are always shown: if the page is fullscreened, or if the dock is configured to automatically hide and show, then they won't be counted in availHeight.Diagram showing how Screen.availHeight relates to Screen.height and the screen's contents

Remarks

You can similarly use AvailWidth to get the number of pixels
which are horizontally available to the browser for its use.

-Screen
-AvailWidth

ColorDepth

The Screen.colorDepth read-only property returns the
color depth of the screen. Per the CSSOM, some implementations return 24
for compatibility reasons. See the browser compatibility section for those that don't.

[Value("colorDepth")]
public ulong ColorDepth { get; }

Property Value

ulong

A number.

[Value("height")]

IsExtended

NOTE

Experimental

The isExtended read-only property of the
Screen interface returns true if the user's device has multiple screens, and false if not.

[Value("isExtended")]
public bool IsExtended { get; }

Property Value

bool

A boolean value — true if the device has multiple screens, and false if not.

NOTE

If a Permissions-Policy/window-management Permissions-Policy is set that blocks use the Window Management API, isExtended will always return false.

Remarks

This property is typically accessed via window.screen.isExtended, and can be used to test whether multiple screens are available before attempting to create a multi-window, multi-screen layout using the Window Management API.
