Now I have some other questions. Is it possible to use svg-files with agile? I loaded up my logo in svg format an can find it correctly displayed in the mediaoverview. But when I try to use it with the theme as site logo I see anything. And the quality of my png-Logo is not really good.
And I want to ask, f it´s possible that the header will not change the format if I scroll down on a single page?
I am not sure how to incorporate svg file for the logo. I would recommend that you use the png file for cross-browser compatibility. For keeping the header and sticky header the same, pls see this post
