I'm trying to create a website and my problem is that I cannot fix the position of the header image on the different pages of the website.
This is the home page: http://www.antransclean.eu/. It's fine, because the header image sticks to the menu above it.
This is an example of another page: http://www.antransclean.eu/szolgaltatasok. There is a white border between the menu and the header image, and I cannot make it disappear. Do you have any idea how I could make the white border disappear? The header image should stick to the menu.
(I am using a modified version of the AccesspressLite Theme.)
Thank you for your help in advance.
