HTML DOM scrollTop Property

The DOM scrollTop property is used to return or set the number of pixels an element is scrolled vertically. If the element’s content doesn’t generate a scroll bar, then its scrollTop value is 0.

Syntax:

It returns the scrollTop property.

element.scrollTop

It is used to set the scrollTop property

element.scrollTop = value

Where value specifies the number of pixels the element’s content is scrolled vertically.

Note:

Its value can’t be negative.
If the value specified is greater than the maximum scroll amount, the value is set to a maximum number.
