Thanks that works but is it possible that every submenu is exactly in the middle under the main menu ?

I have deactivated autoptimize. With this css code there is a change but its only the textcolor not the buttoncolor.

Best regards

ive put this on my css but it doesnt change the color. What could be the reason?

I did everything you said but i cant see anything. The widget area should be placed under the H1 Title on every post.

Here are the informations

Under the color-section with a picture of the cathedral of palma is a big white space. This problem is only on mobile devices.
