I have in my html document several div elements with certain css class and want to get x, y position of those elements, thanks in advance.
The examples bellow show how to retrieve the ClientRect of an HTML Element
# first tag link of this page
document.getElementsByClassName('post-taglist')[0].children[0].getClientRects()[0]
# question div
document.getElementById('question').getClientRects()[0]
With it you have acces to right, top, height, width, left and bottom attributes.
