# Scrolling value of elements in JavaScript

The following properties contain how much the element is scrolled:

`console.log(elem.scrollTop); // from top console.log(elem.scrollLeft); // from left`

The following example shows how these properties work. Scroll the element and click on the button, you will see the scroll amount:

Given an element and a button. By clicking on the button, find out how much the element is scrolled vertically.

Given an element and a button. On button click, check if the element is scrolled vertically.

Scroll to the bottom of the element. Press the button to display the full scroll value.

Get the element's `scrollHeight` and subtract the full scroll amount (take it from the previous task) from it. What will be the value? What dimensions does it contain?

Add `offsetHeight` and the amount of full scroll. Subtract this amount from `scrollHeight`. What number will come out?
