Add :focus where you add :hover in your CSS.
Add focus to an element:
- tabindex: 0 gives focus to items that wouldn’t normally get focus and includes them into normal tab order
- tabindex: -1 gives focus to items that wouldn’t normally get focus and/or removes items from the normal tab order
- tabindex: any positive integer gives focus and overrules normal tab order
Avoid hijacking the tabindex: it makes it very hard for keyboard users to access the menu.
