问题
I added code to hamburger menu below. I want to close menu after click on specific section.
For example, if you click on 'contact' section menu should hide and move me to contact section on page. I waste about one hour and really don't have an idea how to fix it, menu still appears on screen.

回答1:
Instead using a :checked
input which is an issue if you want to unchecked it while you click on a link (make a choice click the input or the link) , you may use :focus
that can easily be lost clicking anywhere else.
Possible example
