Clearly Display Logo

The clearly_display_logo() functions automatically does a margin-top calculation and moves my Logo Icon to a too high position (gets cut off).
I am not using the ‘Logo’ because then my Pagetitle wouldn’t be shown anymore so I need to use ‘Logo Icon’ instead.

Where do I have to adjust this function? I was not able to find it and I cannot overwrite it in the css file since inline css is stronger than the definition of the .logo-icon class.

Please advise.
