I am trying to create a navigation bar similar to the one seen on W3School's website.
I would like the navigation bar to overlap the header when scrolling down, and for the header to appear above the nav bar when scrolling back to the top.
Despite my efforts, I have been unable to achieve the desired result.
I successfully implemented this feature using a CSS class and a small snippet of JavaScript to activate the class.
The concept revolves around comparing the position of the element with the current scroll of the viewport.
For a demonstration, you can visit my CodePen example: http://codepen.io/giacomofurlan/pen/hcfkE
To delve deeper into the specifics, check out my extended explanation here:
Here is the key part - the JavaScript controller (identifying nav#menu as our sticky menu):
(function ($) {
"use strict";
var menuPosition = function () {
var nav = $("nav#menu"),
height = nav.height(),
windowHeight = $(window).height();
if ($(window).scrollTop() > (windowHeight - height)) {
nav.addClass('fixed');
} else {
nav.removeClass('fixed');
}
};
menuPosition();
$(document).scroll(menuPosition);
}(jQuery));
Additionally, here is the accompanying CSS class:
.fixed {
position: fixed;
top: 0px;
}
Are you looking for this solution? If yes, then jQuery can help you achieve it. Don't forget to search on Google before posting anything; there are numerous tutorials available.
$(document).ready(function()
{
window.holdOffset = $('#sticky_navigation').offset().top;
$(window).scroll(function()
{
sticky_navigation();
});
});
function sticky_navigation()
{
var scroll_top = $(window).scrollTop();
if (scroll_top > holdOffset)
$('#sticky_navigation').css({ 'position': 'fixed', 'top':0, 'left':0 });
else
$('#sticky_navigation').css({ 'position': 'relative' });
