I added a sticky Header to my webshop, and it works fine with FF, Chrome, Edge.
In Safari (Windows 10) JavaScript is executed, the header is fixed and transformed - but not visible!
When the Cursor is on the positions of the Menu-Buttons the Tooltips/Link-Titles are showing, also I can use them and click on them.
But its invisible! Because Safari is build by apple I know that´s a feature, not a bug - but it would be very helpful, when the header would be visible to safari-users also!
You can look at it here: https://www.toner-dumping.de - any suggestions?
