How can I determine if a div is scrolled to the bottom?

Question

How do I determine, without using jQuery or any other JavaScript library, if a div with a vertical scrollbar is scrolled all the way to the bottom?

My question is no

Answer 1

Little late to this party, but none of the above answers seem to work particularly well when...

• Display scaling is applied to the OS for UHD displays
• Scaling/zoom is applied to the browser

To accommodate for all eventualities, you will need to round up the calculated scroll position:

Math.ceil(element.scrollHeight - element.scrollTop) === element.clientHeight
