HTML DOM Window scrollX property

Last Updated : 23 Jul, 2020

The scrollX property of the Window interface returns the number of pixels that the document is currently scrolled horizontally in the current window. This value is subpixel precise in modern browsers, meaning that it isn’t necessarily a whole number. This is a read-only property.

Syntax:

var Scrx = window.scrollX

Return Value: The returned value is a double-precision floating-point value indicating the number of pixels the document is currently scrolled horizontally from the origin.

Example: This example shows how to get the precise number of pixels that are being scrolled
horizontally of the document using this property.

Here, We have attached a long horizontal text to exceed the frame to enable scroll horizontally.
