Hello Guenni007 and Rikard,
The test website Guenni007 showed us was exactly what I had in mind. Nothing fancy, just the logo displayed to the left and displayed in full size.
Thanks to Guenni007 I’ve managed to solve the issue by adding the following code to the custom CSS:

@media only screen and (min-width: 990px) {
.av-section-bottom-logo {
margin-top: 30px !important;;
}
.html_header_top.html_logo_center .logo {
left: 15%;
}
}

Hi Rikard,

Thanks for your attempt to solve my issue. Sorry to see it didn’t help. It even made it worse and only would solved just one part of my issue.
Instead of lowering the image it lifts up the logo. And also does not place the logo to the left
Before submitting my ticket I also tried your suggestion combined with my wish to have the logo left aligned. I used the following css code. Which in my opinion should work, but does not.:

.av-section-bottom-logo {
float: left;
margin-top:40px;
}
