jQueryUI position utility

In web-development you often need to work with html, css, javascript.
The most tedious part of this work is to position elements among each other.

What can help you to speed up this work?

I have discovered the position method in jQueryUI library.
This method easily allows you to position given element against selector, element, jquery or event. The last option means that you can also position elements against your cursor.

Hope this help someone.
