Minimizing the menu bar while scrolling down (bootstrap3)

Could anyone help me with creating a navigation-bar effect similar to the one seen on ? I want the bar to shrink and the logo to change after scrolling down my page. My website is built using bootstrap 3. Is there a simple way to achieve this effect with bootstrap?

Creating a Sticky Navbar:

To make your navbar sticky, simply add the navbar-fixed-top class to your navigation element.

For more detailed instructions, refer to the official documentation:
https://getbootstrap.com/docs/5.0/components/navbar/#placement

Check out an official example here:
http://getbootstrap.com/examples/navbar-fixed-top/

Here is a simple code snippet for implementation:

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container">
    ...
  </div>
</nav>

Resizing the Navbar:

If you want the navbar to resize as you scroll down the page, take a look at this helpful example: http://www.bootply.com/109943

Use JavaScript for resizing:

$(window).scroll(function() {
  if ($(document).scrollTop() > 50) {
    $('nav').addClass('shrink');
  } else {
    $('nav').removeClass('shrink');
  }
});

Apply CSS for styling changes:

nav.navbar.shrink {
  min-height: 35px;
}

Implementing Animation:

Add animation effects while scrolling by setting transitions on the navbar element itself.

Use CSS for animation:

nav.navbar{
  background-color:#ccc;
   // Animation
   -webkit-transition: all 0.4s ease;
   transition: all 0.4s ease;
}

You can also use toggleClass in this way:

$(window).on("scroll", function() {
    $("header").toggleClass("reduce", $(this).scrollTop() > 50)
});

For those who prefer Vanilla Javascript over jQuery, here is an alternative way to achieve the same result using the classList property:

function adjustNavOnScroll() {
    var navElement = document.getElementsByTagName('nav');
    if(document.body.scrollTop >= 50) {
        navElement[0].classList.add('shrink');
    } else {
        navElement[0].classList.remove('shrink');
    }
    console.log(topMenu[0].classList);
};

There may be a more elegant solution using toggle, but the above code functions correctly in Chrome

If you want to achieve the desired outcome, you can merge the "scroll" and "scrollstop" events like this:

$(window).on("scroll",function(){
   $('nav').addClass('shrink');
}); 
$(window).on("scrollstop",function(){
   $('nav').removeClass('shrink');
});

If you are utilizing AngularJS along with Angular Bootstrap, you can achieve a sleek design by following the steps below: Visit angular-ui.github.io/bootstrap for more information.

To implement this effectively:

HTML:

<nav id="header-navbar" class="navbar navbar-default" ng-class="{'navbar-fixed-top':scrollDown}" role="navigation" scroll-nav>
    <div class="container-fluid top-header">
        <!--- Additional code here --->
    </div>
</nav>

CSS: (Note: Padding is used to create a collapsible navigation bar. Modify as needed)

nav.navbar {
  -webkit-transition: all 0.4s ease;
  transition: all 0.4s ease;

  background-color: white;
  margin-bottom: 0;
  padding: 25px;
}

.navbar-fixed-top {
  padding: 0;
}

Add the directive below:

Directive: (Note: Adjust this.pageYOffset >= 50 value based on your requirements)

angular.module('app')
.directive('scrollNav', function ($window) {
  return function(scope, element, attrs) {
    angular.element($window).bind("scroll", function() {
      if (this.pageYOffset >= 50) {
        scope.scrollDown = true;
      } else {
        scope.scrollDown = false;
      }
      scope.$apply();
    });
  };
});

This approach will provide a visually appealing and animated effect to your website's navigation.
