[Javascript] Re: Getting the width property of div

[Paul Novitski]

Shawn et al.,

As I recall, the reason for using object.offsetWidth instead of 
object.style.width is that offsetWidth represents the actual current width 
of the rendered object, whereas style.width represents the intended width 
as (and if) defined by a stylesheet or inline style.

With that reasoning, style.width can fail in browsers that allow elements 
to stretch to accommodate their contents in spite of explicit width 
styling, and will fail if the object hasn't been assigned a width in CSS.

Am I remembering this correctly?

Cheers,
Paul
