Dom elements have their current scroll state in their scrollLeft/scrollTop
properties.
document.documentElement.scrollLeft/scrollTop works in most browsers
Luckily, we dont have to remember this verbose at all
alert('Current scroll from the top: ' + window.pageYOffset);
alert('Current scroll from the left: ' + window.pageXOffset);
regular elements can be scrolled by changing scrollTop/scrollLeft.
Alternativelt there is a simpler and universal method exists
window.scrollBy(x,y) : scrolls the page relative to its current position window.scrollTo(pageX,pageY) : scrolls the page to absolute coordinates
