How do you make the background of a bootstrap navbar transparent?

How do you make the background of a bootstrap navbar transparent? - javascript

I'm having trouble making the background of the following navbar transparent. I've tried making background-color: transparent !important; for .navbar but that doesn't seem to work either.
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarnavdropdown" aria-controls="navbarnavdropdown" aria-expanded="false" aria-label="toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarnavdropdown">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="index.html"><img src="assets/img/resultheap-logo.png" alt="" /></a>
</li>
<li class="nav-item">
<a class="nav-link" href="about.html">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="services.html">Services</a>
</li>
<li class="nav-item">
<a class="nav-link" href="blog/index.html">Blog</a>
</li>
<li class="nav-item">
<a class="nav-link" href="faq.html">FAQ</a>
</li>
<li class="nav-item">
<a class="nav-link" href="contact-form/index.html">Contact</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbardropdownmenulink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
dropdown link
</a>
<div class="dropdown-menu" aria-labelledby="navbardropdownmenulink">
<a class="dropdown-item" href="#">action</a>
<a class="dropdown-item" href="#">another action</a>
<a class="dropdown-item" href="#">something else here</a>
</div>
</li>
</ul>
</div>
</nav>

remove the bg-light class from the nav element, or override it inline or id with important. But the cleanest way is to remove simply the class. I think you could simply not override it because bootsstrap sets the color with the bg-light class also with !important.

I don't believe you may have mentioned it but have you tried the the 'opacity' css.
You can do:
opacity: 0; //Makes fully transparent
opacity: 0.5; //Half transparent
opacity 1; //No transparency
Hopefully this helps for the navbar. Let me know if it doesn't, i'll try and help in any way possible.

You can add a new css class as background-color: transparent; or you can change property of ".bg-light" class.
.bg-light {background-color:Transparent!important}

Bootstrap 5: Navbar to the most right [duplicate]

How do I align a navbar item to right?
I want to have the login and register to the right.
But everything I try does not seem to work.
This is what I have tried so far:
<div> around the <ul> with the atribute: style="float: right"
<div> around the <ul> with the atribute: style="text-align: right"
tried those two things on the <li> tags
tried all those things again with !important added to the end
changed nav-item to nav-right in the <li>
added a pull-sm-right class to the <li>
added a align-content-end class to the <li>
This is my code:
<div id="app" class="container">
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav " >
<li class="nav-item">
<a class="nav-link" href="{{ url('/login') }}">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ url('/register') }}">Register</a>
</li>
</ul>
</nav>
#yield('content')
</div>

Bootstrap 5 (update 2021)
In Bootstrap 5 (see this question), ml-auto has been replaced with ms-auto to represent start instead of left. Since the Navbar is still based on flexbox, auto margins OR flexbox utility classes are still used to align Navbar content.
For example, use me-auto...
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Brand</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarContent">
<ul class="navbar-nav me-auto mb-2 mb-lg-0">
<li class="nav-item">
<a class="nav-link active" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false"> Menu </a>
<ul class="dropdown-menu dropdown-menu-end" aria-labelledby="navbarDropdown">
<li><a class="dropdown-item" href="#">Action</a></li>
<li><a class="dropdown-item" href="#">Another action</a></li>
</ul>
</li>
</ul>
</div>
</div>
</nav>
Bootstrap 5 right align Navbar content
Bootstrap 4 (original answer)
Bootstrap has many different ways to align navbar items. float-right won't work because the navbar is now flexbox.
You can use mr-auto for auto right margin on the 1st (left) navbar-nav.
Alternatively, ml-auto could be used on the 2nd (right) navbar-nav , or if you just have a single navbar-nav.
<nav class="navbar navbar-expand-md navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Register</a>
</li>
</ul>
</div>
</nav>
https://codeply.com/go/P0G393rzfm
There are also flexbox utils. For example use justify-content-end on the collapse menu:
<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
<div class="container-fluid">
<a class="navbar-brand" href="#">Brand</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse justify-content-end" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="#">Contact</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Download</a>
</li>
</ul>
</div>
</div>
</nav>
Or when you have 2 navbar-navs, use justify-content-between in navbar-collapse would work to even the space between the navbar-navs:
<div class="navbar-collapse collapse justify-content-between">
<ul class="navbar-nav mr-auto">
..
</ul>
<ul class="navbar-nav">
..
</ul>
</div>
Update for Bootstrap 4.0 and newer
As of Bootstrap 4 beta, ml-auto will still work to push items to the right. Just be aware the the navbar-toggleable- classes have changed to navbar-expand-*
Updated navbar right for Bootstrap 4
Another frequent Bootstrap 4 Navbar right alignment scenario includes a button on the right that remains outside the mobile collapse nav so that it is always shown at all widths.
Right align button that is always visible
Related: Bootstrap NavBar with left, center or right aligned items

In my case, I wanted just one set of navigation buttons / options and found that this will work:
<div class="collapse navbar-collapse justify-content-end" id="navbarCollapse">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Sign Out</a>
</li>
</ul>
</div>
So, you will add justify-content-end to the div and omit mr-auto on the list.
Here is a working example.

For those who is still struggling with this issue in BS4 simply try below code -
<ul class="navbar-nav ml-auto">

On Bootstrap 4
If you want to align brand to your left and all the navbar-items to right, change the default mr-auto to ml-auto
<ul class="navbar-nav ml-auto">

On Bootsrap 4.0.0-beta.2, none of the answers listed here worked for me. Finally, the Bootstrap site gave me the solution, not via its doc but via its page source code...
Getbootstrap.com align their right navbar-nav to the right with the help of the following class: ml-md-auto.

Use this code to move items to the right.
<div class="collapse navbar-collapse justify-content-end">

Use ml-auto instead of mr-auto after applying nav justify-content-end to the ul

Just add mr-auto class at ul:
<ul class="nav navbar-nav mr-auto">
If you have menu list in both side you can do something like this:
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#">left 1</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">left 2</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">left disable</a>
</li>
</ul>

If you want Home, Features and Pricing on left immediately after your nav-brand, and then login and register on right then wrap the two lists in <div> and use .justify-content-between:
<div class="collapse navbar-collapse justify-content-between">
<ul>....</ul>
<ul>...</ul>
</div>

In bootstrap v4.3 just add ml-auto in <ul class="navbar-nav">
Ex:<ul class="navbar-nav ml-auto">

use the flex-row-reverse class
<nav class="navbar navbar-toggleable-md navbar-light">
<div class="container">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false"
aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">
<i class="fa fa-hospital-o fa-2x" aria-hidden="true"></i>
</a>
<div class="collapse navbar-collapse flex-row-reverse" id="navbarNavAltMarkup">
<ul class="navbar-nav">
<li><a class="nav-item nav-link active" href="#" style="background-color:#666">Home <span class="sr-only">(current)</span></a</li>
<li><a class="nav-item nav-link" href="#">Doctors</a></li>
<li><a class="nav-item nav-link" href="#">Specialists</a></li>
<li><a class="nav-item nav-link" href="#">About</a></li>
</ul>
</div>
</div>
</nav>

It's little change in boostrap 4.
To align navbar to right side, you've to make only two changes.
they are:
in navbar-nav class add w-100 as navbar-nav w-100 to make width as 100
in nav-item dropdown class add ml-auto as nav-item dropdown ml-auto to make margin left as auto.

<a class="dropdown-item" href="#">Another action</a>

</ul>
</div>

For bootstrap 4.3.1, I was using nav-pills and nothing worked for me except this:
<ul class="nav nav-pills justify-content-end ml-auto">
<li ....</li>
</ul>

In my case Bootstrap v5, I wanted just one set of navigation options to the right side:
just add "ms-auto" in ul.
And it helped me.
<div class="collapse navbar-collapse" id="navbarCollapse">
<ul class="navbar-nav ms-auto mb-2 mb-md-0">
<li class="nav-item">
<a class="nav-link " aria-current="page" href="index.php">Home</a>
</li>
<li class="nav-item">
<a class="nav-link " href="services.php" tabindex="-1" aria-disabled="true">Services</a>
</li>
<li class="nav-item">
<a class="nav-link" href="aboutus.php">About Us</a>
</li>
<li class="nav-item">
<a class="nav-link" href="Portfolio.php">Portfolio</a>
</li>
</ul>
</div>

The above answers surprisingly didn't work for me so here is my approach. To align the login and register navigation bar items to the right you can make use of either of these two ways:
pull-right:
Modify the unordered list tag for login and register as
<ul class="navbar-nav pull-right">
navbar-right:
Modify the unordered list tag for login and register as
<ul class="navbar-nav navbar-right">

I am running Angular 4 (v.4.0.0) and ng-bootstrap (Bootstrap 4). This code won't all be relevant but hoping people can pick and choose what works. It took me sometime to find a solution to get my items to justify right, collapse properly and to implement a dropdown off my google (using OAuth) profile picture.
<div id="header" class="header">
<nav class="navbar navbar-toggleable-sm navbar-inverse bg-faded fixed-top">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent"
aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">
<img alt='Brand' src='../assets/images/logo-white.png' class='navbar-logo-img d-inline-block align-top '>
<span class="navbar-logo-text">Oncoscape</span>
</a>
<div class="collapse navbar-collapse justify-content-end" id="navbarSupportedContent">
<ul class="navbar-nav float-left">
<a class="navbar-items nav-item nav-link active " *ngIf='authenticated' (click)='goDashboard()'>
<span class="fa fa-dashboard"></span>Dashboard
</a>
<a class="nav-item nav-link navbar-items active" href="http://resources.sttrcancer.org/oncoscape-contact">
<span class="fa fa-comments"></span>Feedback
</a>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<img *ngIf='user && authenticated' class="navbar-pic" src={{user.thumbnail}} alt="Smiley face">
</a>
<div *ngIf='user && authenticated' class="dropdown-menu " aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" (click)="toProfile()">Account</a>
<div class="dropdown-item">
<app-login></app-login>
</div>
</div>
</li>
</ul>
</div>
</nav>
</div>
<router-outlet></router-outlet>

For Bootstrap 4 beta, sample navbar with elements aligned to the right side is:
<div id="app" class="container">
<nav class="navbar navbar-expand-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="{{ url('/login') }}">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ url('/register') }}">Register</a>
</li>
</ul>
</nav>
</div>

Using the bootstrap flex box helps
us to control the placement and alignment of your navigation element.
for the problem above adding mr-auto is a better solution to it .
<div id="app" class="container">
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav " >
<li class="nav-item">
<a class="nav-link" href="{{ url('/login') }}">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ url('/register') }}">Register</a>
</li>
</ul>
</nav>
#yield('content')
</div>
other placement may include
fixed- top
fixed bottom
sticky-top

The working example for BS v4.0.0-beta.2:
<body>
<nav class="navbar navbar-expand-md navbar-dark bg-dark">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Register</a>
</li>
</ul>
</div>
</nav>
<div class="container-fluid">
container content
</div>
<!-- Optional JavaScript -->
<!-- jQuery first, then Popper.js, then Bootstrap JS -->
<script src="node_modules/jquery/dist/jquery.slim.min.js"></script>
<script src="node_modules/popper.js/dist/umd/popper.min.js"></script>
<script src="node_modules/bootstrap/dist/js/bootstrap.min.js"></script>
</body>

If all above fails, I added 100% width to the navbar class in CSS. Until then mr auto wasn't working for me on this project using 4.1.

but the nav item you want to align to right in alone
put it outside the of main nav but in the same , like that:
<ul class="navbar-nav justify-content-end ms-auto">
<li class="nav-item">
<a class="nav-link" href="#" aria-expanded="false">Contact support</a>
</li>
<li class="nav-item ">
<a class="nav-link" href="#" aria-expanded="false">Log in</a>
</li>
</ul>
use justify-content-end ms-auto

Find the 69 line in the verndor-prefixes.less and write it following:
.panel {
margin-bottom: 20px;
height: 100px;
background-color: #fff;
border: 1px solid transparent;
border-radius: 4px;
-webkit-box-shadow: 0 1px 1px rgba(0,0,0,.05);
box-shadow: 0 1px 1px rgba(0,0,0,.05);
}

Just copied this from one of the getbootstrap pages for the released version 4 which worked much better than the above
<div class="d-none d-xl-block col-xl-2 bd-toc float-md-right">
<ul class="section-nav">
<li class="toc-entry toc-h2">Overview</li>
<li class="toc-entry toc-h2">Classes</li>
<li class="toc-entry toc-h2">Mixins</li>
<li class="toc-entry toc-h2">Responsive</li>
</ul>
</div>

I'm new to stack overflow and new to front end development. This is what worked for me. So I did not want list items to be displayed.
.hidden {
display:none;
}
#loginButton{
margin-right:2px;
}
<nav class="navbar navbar-toggleable-md navbar-light bg-faded fixed-top">

i am beginner so I am trying to make a website for just learning the language that was been used is Javascript and faced this problem that dropdown menu hiding behind cards and the filter, any one faced the same problem ? and this is the pics
any help ?
enter image description here

Try increasing the z-index of the dropdown-menu
Like this,
.dropdown-menu{
z-index: 2000 !important;
}

You are facing this issue due to z-index. If you want to display the drop-down menu at the front then you can increase it's z-index so that it won't hide behind any cards. Make sure that z-index is greater than any other element which might hide the drop-down menu. You can read more about it here.

my jquery code
$(document).ready(function(){
// Add active class on navbar link and remove from siblings
"use strict";
$(window).scroll(function(){
$('.block').each(function(){
if($(window).scrollTop() > $(this).offset().top){
// console.log($(this).attr('id'));
var blockId = $(this).attr('id');
$('a.nav-link[href^="#' +blockId+'"]').addClass('active');
$('.nav-link').removeClass('active');
}
});
});
});

You are immediately removing the active class from all links after you set the currently active one. You need to remove the active class from all the other links first, then apply the new one.
Swap the order of these lines:
$('a.nav-link[href^="#' +blockId+'"]').addClass('active');
$('.navbar a').removeClass('active');
Becomes:
$('.navbar a').removeClass('active');
$('a.nav-link[href^="#' +blockId+'"]').addClass('active');
The editor here struggled with your layout, so here's a codepen showing the above: https://codepen.io/29b6/pen/ZErMGpJ?editors=1111
This works fine, but bear in mind that listening to scroll events is quite an inefficient solution, especially as you're just looping over a bunch of DOM elements each time. You might want to read up about the Intersection Observer API for a more passive approach.

this is the code for navbar with dropdowns in bootstrap. but the problem is here dropdown is not working when is a toggle to the navbar dropdown icon
code Link: https://getbootstrap.com/docs/4.0/components/navbar/
any suggestions why it isn't working for react??

You need to use reactstrap npm package together with bootstrap. have a look here: https://reactstrap.github.io/

You should use react-bootstrap. It works fine with react and is specially made for react.

jquery doesn't add class "show" to parent li and doesn't change aria-expanded attribute.
Seems like jquery v3.2.1 not compatible with botstrap v4, but i saw examples which uses this versions.
Please, help me to resolve this problem.

You did not include Popper.js in your markup.
The javascript part of Bootstrap 4 has been built on top of jQuery and Popper.js. As the documentation points it out: "jQuery must come first, then Popper.js, and then our JavaScript plugins". Including Popper.js will eliminate your error.
Additionally, it is also suggested that these <script> tags should go to near to the end of the pages, right before the closing </body> tag.
So your markup should look like this:
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" rel="stylesheet"/>
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>

<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>

</div>
</li>
</ul>
</div>
</nav>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

How do you make the background of a bootstrap navbar transparent? - javascript

remove the bg-light class from the nav element, or override it inline or id with important. But the cleanest way is to remove simply the class. I think you could simply not override it because bootsstrap sets the color with the bg-light class also with !important.

I don't believe you may have mentioned it but have you tried the the 'opacity' css. You can do: opacity: 0; //Makes fully transparent opacity: 0.5; //Half transparent opacity 1; //No transparency Hopefully this helps for the navbar. Let me know if it doesn't, i'll try and help in any way possible.

You can add a new css class as background-color: transparent; or you can change property of ".bg-light" class. .bg-light {background-color:Transparent!important}
