Qv Mashup iframe, CSS/Html width question

[#1]

Hi

I´m not that in to CSS and html. I´m trying to use iframe qv mashups integration and it work´s nice. But I think the main frame / boarder could be a bit more widther. I think that could be set in some of the css-files but I´m qlueless of what I´m looking for...

In the pic below it´s the yellow boarder that I want to expand. Then the loaded qv document could use more of the (yellow) space on the screen.
