This is a function which creates a function which returns the result of invoking the original function and `not`ing it's return value, and then returning that function. | Use the `not` operator in a decorator:

#gestaltung_illu:hover ~ #mainhexa2,

You can do the effect you want only with CSS and HTML ( without javascript ), but you have to place your elements to follow each other and use `+` selector in CSS. Something like :
