header heigoh

Hello Minal, Here you can see how the header is now.       What I should like is to make the white header part less high. This is the first thing I need. Don't know how to do that, not after looking in the support forum or on the internet. I tried to make it very beautiful by adding an image to the header. This had the wrong result. The header image (the same as you see here always want to have the same height, also after making the height 300 instead of 600 px. Consequence: vague image. If you can give me a clue how to to that, it should be great. But first of all I want to make the real header (with site logo and navigation) much smaller. Kind regards Hans Hagmeijer
