top and left values

Question

I tried to replicate some webpages like gmail and Facebook's home page.. I saw the source code on net and i had a query.. How do i determine the value of 'top' and 'left' in px while positioning in css?

Answer 1

You can use offsetTop and offsetLeft properties in JavaScript to determine the top/left values. Or if you are using a library like jQuery, you can use the offset() method to retrieve the top/left values.
