Using dashboard widget inside UI-template?


Default widgets for the dashboard are great , they let you quickly build an UI for the data.
However I have real trouble positioning columns that are 12 wide causing that group/column to overlap over the other columns when they are more then 4
I've tried to override certain css in a custom ui-template but the column position is absolute and is set at element level and my rules get overridden and ignored.
So my question is two fold:
· is it possible to get a hold of the css rules for the dashboard or override them somehow, or other tricks to have a 12 column group correctly displayed when there are >4 number of column?

· is otherwise possible to have the chart, the slider and the gauge widgets inside a ui-template where I can have my custom layout?
