three questions: Background not scrolling when scrolling ...
I have three questions about the website: https://pixelway.de/projekt-elektro-2016/
1. How can I make the website a little higher so that I have less margin at the top?
2. How do I fill in the background of the menu so that the button appears as in the small snippet?
3. Can I set the website so that the background does not scroll when I scroll?
