Closed 5 years ago.
this is my very second question!
I also searched in the questions but nothing helps.
I have a problem with transitions. I am trying to apply a 300ms transition to the menu when the toggle button is checked on mobile view; I tried in vain with negative values in the class .menu. Now, doing so the menu slides up but I want it to slide down and nothing seems to help. I also tried with the z-index but nothing seems to work.
I really can't figure out what to do. Any help that could send me on the right direction would be greatly appreciated!

Answer 1

#menuToggle:checked ~ header .menu {
display: block;
top;
66px;
}
should be
#menuToggle:checked ~ header .menu {
display: block;
top: 66px;
}
