Customizing Marketo Template 2-A

Hello,

I was wondering if anyone can help me with an issue I am having with Template 2-A.  I have increased the font size of the text on the right side of the header and have the button hidden.  When I did this the header section expanded in height.  The problem I have is that the logo on the left looks funny because it seems like the height attribute of this element is static.  I looked in the code for the template and found that it has a min-height and min-width declared for this element.  I have tried adjusting these values but it only changes the size of the element box, not the image itself.  See screen shot:

The image I am using is larger than the min height and min width so it is not a matter of the image not being large enough to fill the area.

If anyone has any ideas I would greatly appreciate it!
