which is linked to this css file ( i have not writen much in css file because i am unable to make any change)
#title{ background-color:#ff4c68;}
h1{ line-height: 1.3;
font-size: 90px;
background-color: yellow; }
i noticed that I was able to change background color but i am unable to change line height, font size,font family of elements such as h1 ,h3 ,h2 etc from external css file but i can style it by inline css. why is that so?Please help.


After you load your stylesheet you are loading a third-party stylesheet from Bootstrap which probably applies its own styles to those elements.
Use the Inspector feature of your web browsers developer tools to look at your h1 element and see which styles are applied to it, in which order, and where they come from.
Remember that styles are applied in the cascade order with rulesets of higher specificity overriding those of lower specificity and when specificity is equal later rulesets overriding earlier ones.
If specifity is equal then simply moving the <link> to your stylesheet so it is added after Bootstrap's will resolve your problem.

Bootstrap 5 JavaScript not working, what did I do wrong?

Pardon me if I am missing something obvious. I am using WebStorm to write a website and wanted to experiment with Bootstrap. Now the problem is that I'm pretty sure the Bootstrap's JavaScript isn't working. For example, I can't toggle a div with a "collapse" class, the Navbar "active" class isn't working as well. Here is my code. UPDATE: updated code, I should also add my javascript is working, but the bootstrap javascript isn't

How do I get the Materialize Feature Discovery Block to show up on my webpage?

I am trying to get the feature block to show up on the page when I click the open button, but it is not doing anything. I have a sneaking suspension this has to do with the CDNs I'm importing and their position. Or this could have something to do with the order of the relevant tap target sections in my code, I'm not really sure. I followed the Materialize example of how to set this up verbatim, yet it seems like I can't quite get it right.

The css to the item required
.pagetwo {
background-color: white;
background-size: cover;
}
.darkNav {
background-color: black !important;
}
And my JS which does not work....
$(function () {
var header = $('.navbar-default .navbar-toggle .icon-bar');
var logo = $('#logo');
var hieghtThreshold = $(".pagetwo").offset().top;
var hieghtThreshold_end = $(".pagetwo").offset().top + $(".pagetwo").height();
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll >= hieghtThreshold && scroll <= hieghtThreshold_end ) {
console.log("WORKS!!!!!");
//logo.attr("src","/images/Logo-black.png");
//header.addClass("darkNav");
} else {
alert("IT BROKE!");
//logo.attr("src","/images/Logo.png");
//header.removeClass("darkNav");
}
});
})

This will execute every time when the window is scrolled. Go to the magic threshold and see that the WORKS!!!!! comment comes in the console. Replacing alert() with console.log() will throw nice light on it.
The $(window).scroll() fires continuously while scrolling the page. So since you have used alert() it keeps firing every time you scroll, and shows you BROKE!.

Bootstrap Responsive Nav Bar

I am probably missing something quite small and it's frustrating me as I have been sitting here for a few hours now trying to work this out. The Navbar will not link with the Javascript. The button appears when the window is resized correctly however will not collapse the menu when clicked.
Quick look at my Links in my Header (Just in case they are in the wrong order)
<link rel="stylesheet" href="/assets/css/bootstrap.css">
<link rel="stylesheet" href="/assets/css/bootstrap-responsive.css">
<link rel="stylesheet" href="/assets/css/style.css?v=2">
<script src="/assets/js/bootstrap.js"></script>
<script src="/assets/js/bootstrap.min.js"></script>
<!-BootStrap--><script src="/assets/js/jquery-1.7.1.min.js"></script>
<script src="/assets/js/jquery.validate.min.js"></script>
<script src="/assets/js/script.js"></script>
<script src="/assets/js/bootstrap-fileupload.js"></script>
Quick look at my HTML -
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<!--<button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">-->
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<div class="span4">
<a href="{site_url}" title="People Team">
<img src="/assets/img/logo.png" alt="People Team Logo" />
</a>
</div>
<nav>
<div class="nav-collapse">
<ul class="nav">
<li{if segment_1 == ""} class="active"{/if}>
Home
</li>
<li{if segment_1 == "services"} {/if}>
Services
</li>
<li{if segment_1 == "about"} {/if}>
About the team
</li>
<li{if segment_1 == "contact"} {/if}>
Contact Us
</li>
</ul>
</div>
I assumed the Javascript is within the Bootstrap.min.js or Bootstrap.js files which are required for the navbar to work. I am just about stumped. Any help would be appreciated.
Cheers,

Change the order that your JS loads in. jQuery first, bootstrap plugins second.
<script src="/assets/js/jquery-1.7.1.min.js"></script>
<script src="/assets/js/bootstrap.js"></script> -- remove, as it is not really needed when including the minified version
<script src="/assets/js/bootstrap.min.js"></script>
