After centering the menu in style.css, the sub menu fell apart, what to do?

Question

css

Answer 1

Most likely the sub-items of the menu as descendants were passed the CSS properties that you applied to the main menu. Avoid formatting with contextual selectors of the form: .class p, they can harm the descendants of the selectors. To specify which selector the CSS rules should apply to, use child selectors of the form : .class>p>li. To change exactly why the items of interest are displayed the way they are, and not otherwise they can be explored. In Firefox, this is done like this - right-click on the element of interest - explore the element.
