Resize/stretch html element on dragging from one of its corner.

Hi

I need to resize my html element (say div) by stretching it from only one corner, so when I stretch it (drag one of its side) need to fire event on which I would make some CSS updates. I have searched by looking re-sizeable in jQuery but not got the desired result . Here is What I need something similar.

I believe I am not getting proper search result because of wrong terminology, is it stretching, dragging or resizing?

Any link, suggestion, hint would be very helpful Thanks
