How to make all the buttons active in Bootstrap Navbar - javascript

I have the following code:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Case</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
</head>
<body>
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="#">WebSiteName</a>
</div>
<div>
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Page 1 <span class="caret"></span></a>
<ul class="dropdown-menu">
<li>Page 1-1</li>
<li>Page 1-2</li>
<li>Page 1-3</li>
</ul>
</li>
<li>Page 2</li>
<li>Page 3</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><span class="glyphicon glyphicon-user"></span> Sign Up</li>
<li><span class="glyphicon glyphicon-log-in"></span> Login</li>
</ul>
</div>
</div>
</nav>
<div class="container">
<h3>Right Aligned Navbar</h3>
<p>The .navbar-right class is used to right-align navigation bar buttons.</p>
</div>
</body>
</html>
If you run the code you can notice all the buttons (e.g. WebsiteName, Page1,2,3, signup and login) are all grey. Except HOME. How can I deactivate the grey buttons?


See below.
But this is not the best case to go. Better to do global changes in CSS.

You need to override the default gray color to white. The active state you are referring to is irrelevant here as it is a functionality rather than presentation. The changes need to be done to the CSS.
.navbar.navbar-inverse .navbar-brand {
color: #fff;
}
.navbar.navbar-inverse .navbar-nav > li > a {
color: #fff;
}

You have two typos
il instead of li and fadeout instead of fadeOut and you unnecessary load myscript.js as a <link rel="stylesheet" - you can remove that line
If I add the JS and CSS and insert your header it works:
$(function() {
$('ul.nav li.dropdown').hover(function() {
$('.dropdown-menu', this).fadeIn();
}, function() {
$('.dropdown-menu', this).fadeOut('fast');
});
});
$(function() {
$('ul.nav li.dropdown').hover(function() {
$('.dropdown-menu', this).fadeIn();
}, function() {
$('.dropdown-menu', this).fadeOut('fast');
});
});

Twitter Bootstrap 3 navbar dropdown menu not toggling

I am messing around trying to make a custom bootstrap 3 website however I'm currently stuck up on this dropdown menu. I have tried everything from using the web CDN instead of my local files, copying other peoples dropdown code and nothing seems to want to work.

importing header.html into every html page

</li>
</ul>
</div>
</div>
</nav>
</body>
</html>
in my index1.html file I have this:
<html lang="en" ng-app="myApp">
then inside the body tag
<div appheader></div>
i understand this question has already been asked, hence my implementation. but i keep getting this error in the console: Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.3.14/$injector/modulerr?p0=myApp&p1=Error%3A%…gleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.14%2Fangular.min.js%3A17%3A381)
this is the code at the top of my index1.html file which might be causing issues:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">

<script src="http://code.angularjs.org/angular-1.0.1.min.js"></script>
<link href="css/index1.css" rel="stylesheet">
and here is my main.js:
angular.module('myApp')
.directive('appheader', function() {
return {
templateUrl: 'header.html'
};
});

If this is your main.js
angular.module('myApp')
.directive('appheader', function() {
return {
templateUrl: 'header.html'
};
});
you need to create module
angular.module('myApp',[])

Strange spacing in twitter bootstrap top navbar

I've been using Twitter Bootstrap to create a navbar across the top of a page which has several dropdown menus. For some reason, the first list element aligns to the bottom of the bar by virtue of a empty link that fills the top space. I copied this first term for the other list items, but none of the other elements align to the bottom or have an empty link. Any ideas for how i can fix this?

bootstrap drop down menu doesn't open

I am having trouble getting my dropdown's to work. I can get the navbar to show up perfectly, but when I click on "Dropdown" (either of them) it does not display the dropdown menu. I have tried looking on other posts about this, but nothing that fixed everyone's problems helped.

In my case, I loaded bootstrap JS twice. Removed duplicate one and it worked.

The problem is in your stylesheet or bootstrap js Link (look at below). Check again!
<script type="javascript" src="dist/js/bootstrap.js"></script>
<link href="dist/css/bootstrap.css" rel="stylesheet">

I get this to work:

I used the code from http://getbootstrap.com/components/#navbar.
And i get an Error with your jquery version so i used also the link from getbootstrap.com

I tried openning you code with jsFiddle and it worked perfectly.
maybe there is a problem with one of your bootstrap files..?
Try downloading another bootstrap js file
Here is the working example - https://jsfiddle.net/ckcrogo6/ (The HTML code is exactly the same as the code you posted)
Used the bootstrap files found here - https://www.bootstrapcdn.com/

<div class="navbar-wrapper"><!-- navbar start -->
