$(document).ready(function() {
$(".nav-item a").click(function() {
let active = $(".active-nav-item")
if (active) {
$(active).removeClass("active-nav-item");
$(this).parent().addClass("active-nav-item");
}
})
})

#topbar {
.topbar-social-list {
display: flex;
list-style: none;
padding: 0;
margin: 0;
text-align: center;
.topbar-social-list-item {
cursor: pointer;
transition: all 0.3s;
i {
transition: all 0.3s;
