I've implemented a navbar that changes its size on scroll by adding a class called "shrink". While it's functioning correctly, I find the resizing happens too quickly and doesn't look smooth. I want to make the shrinking animation smoother but haven't been successful so far. Here is my current code:
$(window).scroll(function() {
if ($(document).scrollTop() > 50) {
$('nav').addClass('shrink');
} else {
$('nav').removeClass('shrink');
}
});
body {
padding-top: 50px;
min-height:800px
}
nav a {
padding-top: 20px !important;
padding-bottom: 20px !important;
font-size: 18px;
}
nav .navbar-toggle {
margin: 13px 15px 13px 0;
}
.navbar-brand {
font-size: 30px;
}
nav.navbar.shrink {
min-height: 35px;
}
nav.shrink a {
padding-top: 10px !important;
padding-bottom: 10px !important;
font-size: 15px;
}
nav.shrink .navbar-brand {
font-size: 25px;
}
nav.shrink .navbar-toggle {
padding: 4px 5px;
margin: 8px 15px 8px 0;
}
