Brilliant!After uploading the blank png it this finally works.But this is only for the site-title img.
What code do I have to add/change to use svg's this way, for several other icons or svg-images anywhere on a site?(I got this kind of working via Markup, but then on mobile the svg takes the whole screen. So how do I adjust the required sizes for svg's somewhere else on the site?)
Is it possible to add several svg's into Design/ Custom CSS/ Manage Custom Files/ Add images? And if so, how to refer to these url's?Thanks sofar!
