Sample html file no effect

[maxmas]

Hello,
I download ZIP file, and review your index.html,
but nothing is changed in IE8 and Chrome.
No line is auto break.

On your browser, does the javascript insert <span style="display: inline-block;"> to the line?
Also, try changing the browser width to see if the effect applied. The automatic line break only happens on edge of the page width.
