Page header font

I'm trying to change the font type, size, and postion in the page header. I've figured out how to change the size of the header. I'm made it smaller by adjusting the px in the layout.php. However, the size and position of the text stays the same. Please help me to find where to change the size, type, and position of the font in the header.
