OnClick hide navbar - css

Question

I have this navbar and it works fine on computer screen, because of :hover. But on mobile screen you have to click on navbar to open it. I want to hide navbar when li is selected. But I'm not sure how to do it :/ I have to make main-menu width 60px and overflow hidden. I made it with javasript but it works only once. If you want to open it again, the width and overwflow ofc stays the same.
.fa {
position: relative;
display: table-cell;
width: 60px;
height: 36px;
text-align: center;
vertical-align: middle;
font-size:20px;

.stick{
position: sticky;
top: 0;
bottom: 0;
}
.main-menu:hover,nav.main-menu.expanded {
width:250px;
overflow:visible;
}

overflow: hidden !important;

document.getElementsByTagName("body")[0].onclick = function(event){
if(event.target.offsetParent.offsetParent.tagName == "LI"){
document.getElementsByClassName("main-menu")[0].style.width = "60px";
}
}
document.getElementsByClassName("main-menu")[0].onmouseover = function(event){
this.style.width = "250px";
this.style.overflow = "visible";
}
