Bootstrap 3 - Dynamic affix and transparent collapse bar - javascript

I was looking for very long time for pretty solution for dynamic affix with Bootstrap 3 and finally my simply solution is below. Everything works great, except one feature. When i resize website to mobile and expand menu, whole list of menu items is transparent. When i starting scroll down, after the moment when navbar is affixed transparent problem does not exist. I read some posts that it can be caused by relative position for navbar but dont know how resolve this problem and dont loss my functionality.
<div id="nav-wrapper">
<div id="nav" class="navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class=" collapse navbar-collapse navbar-center" id="myNavbar">
<ul class="nav navbar-nav">
<li class="active">ZESPÓL</li>
<li>ZAPLECZE</li>
<li>GALERIA</li>
<li>MATERIALY</li>
<li>KONTAKT</li>
</ul>
</div>
</div>
</div>
<!-- navbar -->
</div>
js:
function myaffix() {
var affixoffset = $('.navbar-inverse').offset().top
$('#nav-wrapper').height($(".navbar-inverse").height());
$(window).scroll(function() {
if ($(window).scrollTop() <= affixoffset) {
$('.navbar-inverse').removeClass('affix');
} else {
$('.navbar-inverse').addClass('affix');
}
});
};
$(document).ready(function() {
myaffix();
$(window).on("resize", function() {
myaffix();
});
});
and part of my css:
#nav.affix {
position: fixed;
top: 0;
width: 100%
}
#nav > .navbar-inner {
border-left: 0;
}
.navbar-toggle
{
float:none;
}
.navbar-header
{
text-align:center;
}
.navbar-inverse .navbar-nav {
display: inline-block;
float: none;
vertical-align: top;
}
.navbar-inverse .navbar-collapse {
text-align: center;
}

Navbar fixed when scroll. With javascript

I don't code javascript so it is a problem for me to understand how to develop my navbar to look like this: http://www.bootply.com/kD5wiG5udv
I have obviously used common sense and swapped my selectors but it still isn't working. Could someone please advise me on what steps to take next?
Please use the above website to navigate through my code as I am not going to add the bootstrap files to this post. They are too large.

<nav class="navbar navbar-default" role="navigation" id="nav">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle Navigation</span>
<span class="icon-bar"></span>

<li><a href="#">Services</li>
<li><a href="#">About</li>
<li><a href="#">Contact</li>
</ul>
</div>
</div>
</nav>
CSS:
.navbar-default
{
background-color: #fbfbfb;
}
.navbar-nav {
float:none;
margin:0 auto;
display: block;
text-align: center;
}
.navbar-nav > li {
display: inline-block;
float:none;
}
.scroll-top {
position:fixed;
bottom:0;
right:6%;
z-index:100;
background: #f2f3f2;
font-size:24px;
border-top-left-radius:3px;
border-top-right-radius:3px;
}
.scroll-top a:link,.scroll-top a:visited {
color:#222;
}
.navbar-nav {
margin-left: 50px;
margin-top: -5px;
}
Javascript:
/* affix the navbar after scroll below header */
$('#nav').affix({
offset: {
top: $('header').height()-$('#nav').height()
}
});
/* highlight the top nav as scrolling occurs */
$('body').scrollspy({ target: '#nav' })
/* smooth scrolling for scroll to top */
$('.scroll-top').click(function(){
$('body,html').animate({scrollTop:0},1000);
})
/* smooth scrolling for nav sections */
$('#nav .navbar-nav li>a').click(function(){
var link = $(this).attr('href');
var posi = $(link).offset().top;
$('body,html').animate({scrollTop:posi},700);
});
In my opinion it would be great to do as much as possible in CSS if your website does not to be compatible with old versions of the browsers. I'm not sure if the Bootstrap has it's own way to implement something similar, but here you can get the idea on how you'd do this yourself.
The main role of jQuery here would be just to add a class on scroll event, which would trigger an animation of opacity. This should be much cleaner solution for the problem as it would be smooth and fast. Here is the working fiddle: https://jsfiddle.net/q5jo781c/1/
This part toggles class on scroll:
$(document).ready(function(){
$(document).scroll(function(){
var st = $(this).scrollTop();
if(st > 200) {
$("navbar").addClass('fixed');
} else {
$("navbar").removeClass('fixed');
}
});
});
And the CSS:
navbar {
width: 100%;
display: block;
height: 50px;
background-color: black;
}
navbar.fixed {
position: fixed;
top: 0;
left: 0;
background-color: white;
animation-name: example;
animation-duration: 1s;
}
#keyframes example {
from {opacity: 0;}
to {opacity: 1;}
}
You can find more of the CSS in the fiddle. Hope it helps.

Bootstrap nav-bar aligned center

Here's my fiddle of my html/bootstrap code.
<body>
<h1 style="text-align:center">AntwerPay</h1>
<!--Navbar-->
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">AntwerPay</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav">
<li class="">Home</li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
Gebieden
<span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li>Gebied 1</li>
</ul>
</li>
<li>Alle Gebieden</li>
</ul>
</div>
</div>
</nav>
</body>
As you can see in my navbar everything is aligned real nicely to the left. This is a problem for me. I want the navbar-brand to be on the left, and i want the 3 other buttons to be centered. I have researched this a lot and found various .css codes but none worked for me.
You can do this using CSS, I've included a suggestion for manually adjusting the position of the items:
.navbar .navbar-nav {
display: inline-block;
float: none;
vertical-align: top;
/* You'd have to adjust this whenever an item is added to the nav-bar */
margin-right: 10%;
}
.navbar .navbar-collapse {
text-align: center;
}
This has been answered already here
Along with your (Again) updated fiddle here
use this snippet
.navbar-bav { float: none !important; text-align:center; }
.navbar-nav > li { display:inline-block; float: none !important; }
Updated fiddle
Remember
If you do NOT know how to make the navbar responsive, then implement the codes above in a #media (min-width: 768px) query in order not to fail the responsiveness of Bootstrap Navbar.
Hope this works for you:
#myNavbar {
text-align: center;
}
.navbar-nav {
margin: 0 auto;
display: inline-block;
float: none;
}
Make shure to keep an eye on the mobile view.

Bootstrap responsive - Textfield not receiving focus

I am using Bootstrap 3, my code is below. Shrink your browser to a small screen view. Click the Search icon, a search field will appear. I am trying to make this textfield receive focus, but I don't see it! $("#search_field").focus(); is not working. I think the problem is because the search button itself gets the focus, and I don't know how to give it to my textfield. Help!

Bootstrap navbar dropdown displaying menu-items horizontally

I've been working on a new project where a navbar required to be center of the page at top. I have the following html...
<div class="navbar navbar-inverse navbar-fixed-top center">
<div class="container navbar-inner">
<div class="navbar-header">
<button class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle Navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div> <!-- //.navbar-header -->
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li>Home</li>
<li>About</li>
<li>Project</li>
<li>Resume</li>
<li>Contact</li>
</ul>
</div> <!-- //.collapse -->
</div> <!-- //.container .navbar-inner -->
</div> <!-- //.navbar -->
and css, which sets the menu-items to center.
html, body {
margin: 0;
padding: 0;
width: 100%;
}
.container {
margin: 0;
padding: 0;
}
.center.navbar .nav,
.center.navbar .nav > li {
float:none;
display:inline-block;
*display:inline; /* ie7 fix */
*zoom:1; /* hasLayout ie7 trigger */
vertical-align: top;
}
.center .navbar-inner {
text-align: center;
}
However the dropdown toggle function seems to display the options horizontally upon medium screen size. (can't post picture...not enough reputation~sorry!)
How can I get the dropdown toggle function to display menu-items vertically as a list (how the default should be) without affecting menu-items being centered on desktop screen size? Any help would be appreciated!!
You should wrap your custom CSS code inside media queries.
#media (min-width: 992px) will affect the elements only in desktop screen size. Learn more about the Grid system

Change logo on scroll Jquery

All right? First of all I want to thank the help. Well, my question is as follows:
I would like to to scroll the mouse and create a background and decrease the space from the top, also change the logo. The question of the top bottom and then I could do as code below. However, I do not know what to do to change the logo.
HTML:
<div class="col-md-12">
<div class="navbar-header page-scroll">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<!-- copy into bootstrap -->
<span class="bar1"></span>
<span class="bar2"></span>
<span class="bar3"></span>
<span class="bar4"></span>
<!-- end of code for bootstrap -->
</button>
<h1 class="navbar-brand-spacing">
<a class="navbar-brand navbar-brand page-scroll" href="" title=""></a>
</h1>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
</div>
</div>
CSS:
.navbar-brand {
text-transform: none;
margin: 0px;
min-width: 214px;
text-indent: -9999px;
height: 70px;
background: url(../images/logo-telbox.png) no-repeat;
}
.navbar-brand-scroll {
background: url(../images/logo-telbox-scroll.png) no-repeat;
}
JS:
$(window).scroll(function () {
var e = $(this).scrollTop();
e > 60 ? $("header").css("background", "#16181F").css("padding", "0px 0px 10px") : $("header").css("background", "transparent").css("padding", "20px 0px 20px");
});
Thanks :)
So, first off, you have the same class added twice here - <a class="navbar-brand navbar-brand page-scroll" href="" title=""></a>
You may do the following to toggle a class based on the scrollTop
.navbar-brand {
text-transform: none;
margin: 0px;
min-width: 214px;
text-indent: -9999px;
height: 70px;
background: url(../images/logo-telbox.png) no-repeat;
}
.navbar-brand.navbar-brand-scroll {
background: url(../images/logo-telbox-scroll.png) no-repeat;
}
var $header = $("header");
var $logo = $("h1.navbar-brand-spacing > a");
$(window).scroll(function () {
var e = $(this).scrollTop();
if (e > 60) {
$header.css("background", "#16181F").css("padding", "0px 0px 10px");
$logo.addClass('navbar-brand-scroll');
} else {
$header.css("background", "transparent").css("padding", "20px 0px 20px");
$logo.removeClass('navbar-brand-scroll');
}
});
P.S. Scroll triggers for every pixel scrolled and way too much scripts on scroll may choke your browser. Use it sparingly!
