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.
