How to center div with Bootstrap CSS
As known most of software developer, Bootstrap Css is one of the best Css tool (especially for me, because I hate gui design).
While using row and span element of this library, I want my div to place on center of page. With my noobish knowledge, i just can type <center></center>. However, this element is deprecated html element and I have to do something more efficient and professional.
Finally I found how to do this by means of https://github.com/twitter/bootstrap/issues/399.
As you see from the issue link, span and offset is really good combo.
