How to Bootstrap navbar static to fixed on scroll?

Question

I would like to make static navbar to fixed navbar on scroll, when it reaches top of the page.

Is there a way to get it using bootstrap 3 css or javascript?

Answer 1

If I'm not wrong, what you're trying to achieve is called Sticky navbar.

With a few lines of jQuery and the scroll event is pretty easy to achieve:

$(document).ready(function() {

    var menu = $('.menu');
    var content = $('.content');
    var origOffsetY = menu.offset().top;

    function scroll() {
        if ($(window).scrollTop() >= origOffsetY) {
            menu.addClass('sticky');
            content.addClass('menu-padding');
        } else {
            menu.removeClass('sticky');
            content.removeClass('menu-padding');
        }
    }

    $(document).scroll();

});

I've done a quick working sample for you, hope it helps: http://jsfiddle.net/yeco/4EcFf/

To make it work with Bootstrap you only need to add or remove "navbar-fixed-top" instead of the "sticky" class in the jsfiddle .

Answer 2

Use the affix component included with Bootstrap. Start with a 'navbar-static-top' and this will change it to fixed when the height of your header (content above the navbar) is reached...

$('#nav').affix({
      offset: {
        top: $('header').height()
      }
});

Answer 3

I am note sure, what you are expecting. Have a look at this fiddle, this might help you.

http://jsfiddle.net/JK52L/8/

You HTML should have the class navbar-fixed-top or navbar-fixed-bottom .

HTML

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
  <!-- Brand and toggle get grouped for better mobile display -->
  <div class="navbar-header">
    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Brand</a>
  </div>

  <!-- Collect the nav links, forms, and other content for toggling -->
  <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
    <ul class="nav navbar-nav">
      <li class="active"><a href="#">Link 1</a></li>
      <li><a href="#">Link 2</a></li>
    </ul>
  </div><!-- /.navbar-collapse -->
</nav>

JS

$(document).scroll(function(e){
    var scrollTop = $(document).scrollTop();
    if(scrollTop > 0){
        console.log(scrollTop);
        $('.navbar').removeClass('navbar-static-top').addClass('navbar-fixed-top');
    } else {
        $('.navbar').removeClass('navbar-fixed-top').addClass('navbar-static-top');
    }
});

Answer 4

Here's a solution using Bootstrap's affix plugin:

HTML:

<header class="container-fluid">
    ...
</header>
<nav class="navbar navbar-default navbar-static-top" role="navigation">
    ...
</nav>

Javascript:

$('nav').affix({
      offset: {
        top: $('header').height()
      }
});

Set padding-top to your body equal to that of your nav 's height so that the content overlayed by the fixed navbar is visible.

$('nav').on('affix.bs.affix', function (){
     $('body').css('margin-top', $('nav').height());
});

$('nav').on('affix-top.bs.affix', function (){
     $('body').css('margin-top', 0);
});

To get the nav to stick on top while scrolling add this bit of CSS.

CSS:

.affix
{
    top: 0;
}

Answer 5

I faced the same problem but the solution that worked for me was:

HTML:

<header class="container-fluid">
    ...
</header>
<nav class="row">
    <div class="navbar navbar-inverse navbar-static-top">
        ...
    </div>
</nav>

JavaScript:

document.onscroll = function() {
    if( $(window).scrollTop() > $('header').height() ) {
        $('nav > div.navbar').removeClass('navbar-static-top').addClass('navbar-fixed-top');
    }
    else {
        $('nav > div.navbar').removeClass('navbar-fixed-top').addClass('navbar-static-top');
    }
};

Where header was the banner tag above my navigation bar

Answer 6

在导航上设置

style="position:fixed; width:100%;"

Answer 7

Or you can change position of specific div using class name

$(document).scroll(function(e){
    var scrollTop = $(document).scrollTop();
    if(scrollTop > 0){
        //console.log(scrollTop);
        $('.header').css("position","fixed");
    } else {
         $('.header').css("position","relative");
    }
});

Answer 8

hey all everyone is over thinking this all you need to do is wrap the nav in a like below:

csscode:

#navwrap {  
    height: 100px;   (change dependant on hight of nav)
    width: 100%;
    margin: 0;
    padding-top: 5px;
}

HTML:

<div id="navwrap">
    nav code inside
</div>

Answer 9

/** * Scroll management */ $(document).ready(function () {

// Define the menu we are working with
var menu = $('.navbar.navbar-default.navbar-inverse');

// Get the menus current offset
var origOffsetY = menu.offset().top;

/**
 * scroll
 * Perform our menu mod
 */
function scroll() {

    // Check the menus offset. 
    if ($(window).scrollTop() >= origOffsetY) {

        //If it is indeed beyond the offset, affix it to the top.
        $(menu).addClass('navbar-fixed-top');

    } else {

        // Otherwise, un affix it.
        $(menu).removeClass('navbar-fixed-top');

    }
}

// Anytime the document is scrolled act on it
document.onscroll = scroll;

});

Answer 11

set max-height as you need:

.navbar-fixed-top 
.navbar-collapse, 
.navbar-fixed-bottom 
.navbar-collapse {
    max-height: 700px;
}

Answer 12

Here is my implementation using the Affix Bootstrap plugin http://getbootstrap.com/javascript/#affix

It includes some extra affix problems solved (see below).

HTML:

<nav class="navbar navbar-inverse navbar-fixed-top" id="top_navbar">
  <div class="container-fluid">
... (typical Bootstrap top navbar)
  </div>
</div>

...
...
...

<div id="parent-navbar-main" >
  <div id="navbar-main">
... (here is your nav panel to get sticky on scroll)
  </div>
</div>

Javascript:

function set_sticky_panel()  {

  var affixElement = $('#navbar-main');

  var navbarElementHeight = $('#top_navbar').height();

// http://stackoverflow.com/questions/18683303/bootstrap-3-0-affix-with-list-changes-width
  var width = affixElement.parent().width();
  affixElement.width(width);

// http://stackoverflow.com/questions/3410765/get-full-height-of-element
  var affixElementHeight = $('#navbar-main').outerHeight(true);

// https://finiteheap.com/webdev/2014/12/26/bootstrap-affix-flickering.html  
  affixElement.parent().height(affixElementHeight);

// http://stackoverflow.com/questions/23797241/resetting-changing-the-offset-of-bootstrap-affix
  $(window).off('.affix')
  affixElement.removeData('bs.affix').removeClass('affix affix-top affix-bottom')


  affixElement.affix({
    offset: {
    // Distance of between element and top page
      top: function () {
      // how much scrolling is done until sticking the panel
        return (this.top = affixElement.offset().top - parseInt(navbarElementHeight,10))
      }
    }
  });

  // The replacement for the css-file.
  affixElement.on('affix.bs.affix', function (){
  // the absolute position where the sticked panel is to be placed when the fixing event fires (e.g. the panel reached the top of the page).
    affixElement.css('top', navbarElementHeight + 'px');
    affixElement.css('z-index', 10);
  });

}

$(document).on('ready', set_sticky_panel);

$(window).resize(set_sticky_panel);

CSS:

No css is required.

If to compare with the standart implementation my code additionaly solves these problems:

1. The width of the sticky panel does not break at the fixing event anymore.
2. The need in the CSS-file usage is eliminated.
3. Reformatting the sticky panel size on the window change size event (responsiveness) is done now.
4. No more affix flittering / jumping at the fixing event.

Answer 13

If you handle the code like this:

<div class="scroll"> 
<div class="menu">home | services | contact</div>
</div>

And css:

.scroll {
  margin-bottom:50px;
}
.menu {
  position:absolute;
  background:#428bca;
  color:#fff;
  line-height:30px;
  letter-spacing:1px;
  width:100%;
  height:50px;
}
.menu-padding {
  // no  style here anymore 
}

Then the annoying scroll is gone.

The compleet code and fiddle is not originally made by me, I got it from an earlier answer in this topic. The change in the code is made by me

Answer 14

The question is a bit older, it's solved by CSS and latest bootstrap natively.

If you add the class sticky-top to your navbar it will behave just like the javascript/jquery in the best current answer but without any javascript.
Browser support is quite decent but not perfect.

Answer 15

If you are using Bootstrap 4, which is the latest version as writing this answer, the assingments have changed a bit. Here is an example of a navbar fixed on top:

<nav class="navbar fixed-top navbar-light bg-light">
    <a class="navbar-brand" href="#"><h1>Navbar</h1></a>
</nav>

Answer 16

Fixed to top

Make bootstrap navbar fixed on scroll

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