Change Header Size

Hello Kriesi Support,

I have a quick problem regarding my header logo. I want to make the transparent header logo bigger, while still keeping the shrink effect when scrolling down.

#header_main .container, .logo, .logo a, .logo img {
min-width: 400px;
}
I found this while searching for a solution. Surely it does change the header image, but only adjust the width (while the height is restricted by the navigation/header bar) and is not shrinking anymore after I set the variables fix. I need to find a solution to make the navigation/header logo bigger, and still make it go small when scrolling.

Any ideas? ;)

All the best,
Niko
