Answer 1

Try this if works
document.getElementById("dn").scrollTop += "10";

also add some content to it to see effect better way

Answer 2

Also don't forget to change the quotation marks between 10 in line 12.

Or else each time you press it it would add two strings like
"10" + "10" = "1010"

Answer 3
