New plugin does not resize

Upgraded to version 2.8 and activated Page Plugin-New. It works EXCEPT that I have tried to re-size the widget to fit properly within the sidebar but it will not re-size. See beyondtheedgefitness.com/team to see the problem; the widget is too wide for its own border. Have reduced the width to as little as 75 px with no change. I resized the sidebar from 250 to 300 to accommodate it but that does not change the fact that the widget control does not work. Look forward to your input.
