I'm trying to achieve a 'collapse icon' that's floated left followed by Copyright © using Bootstrap4.
I've seen other questions about this topic but none seem to actually answer the question. Other questions have different code with obvious typos, my code doesn't. Why is it that data-toggle & data-target aren't recognized when you do include all the dependencies?
.titleText{
font-size:230%;
color:green;
font-weight:heavy;
letter-spacing:1px;
}

The button isn't showing up, just the map & cart text. If you have a workaround I would appreciate a vanilla JS solution apposed to JQuery, since I'm not that experienced with JQuery and would rather use Javascript. Button
Fixed the typo and updated HTML to show collapsible navBar

if you use class text-success in your code, so you cant see navigation bar background-color and default link color so i replace text-sucesss to navbar-light bg-light.

I have made some typo corrections, the toggle functionality now works with this code. But additional modifications are needed to align the elements correctly.

The navbar works fine on the big screen but when you go to a mobile screen the collapse closes back after pressing the collapse icon.

Just update the CDN link for your JavaScript to match the CSS. Both need to be on the 4.x version.

it is just a supplement to the answer of #isherwood and #MrUpsidown.
Indeed, you have incompatible css, jquery and bootstrap versions in your code.
If you want to use the latest version of Bootstrap, you should do like in an example from the answer above. It means you need the same version of css as the version of bootstrap is, 4.3.1. It is also recommended to use jquery slim build. You could read more on the 'Getting started' guide for Bootstrap 4.3.
If you actually need the bootstrap 3.4.1 (that actually was a typo in your code, I believe), you need different css and jquery for it as it follows from the 'Getting started' guide for Bootstrap 3.4 An example of navbar for that version of bootstrap you can find here.
In this case your code will be something like this:

But be careful. 3.4.1 and 4.3.1 are actually different versions :) Good luck with that!
I would like to built a basic website.
Î’elow I have the nav.html document where I have designed a basic dropdown menu. When I open the nav.html with the browser the toggle button works fine, when I click on it,dropdown menu collapses and
when I click on it again drop-down disappears.
The problem appears when I include nav.html in a home.php file.
When I click on the toggle button, dropdown-menu collapses, but when I click on it again dropdown-menu remains open and doesn't disappear.

You are including HTML in HTML and this is not supported. As you are including nav.html into home.php, you want to remove tags body, html and completly head.
<nav class="navbar navbar-light bg-lignt">
<button class="navbar-toggler ml-auto" type="button" data-toggle="collapse" data-target="#collapsingNavbar2">
<span class="navbar-toggler-icon my-toggler"></span>

<div class="navbar-collapse collapse" id="collapsingNavbar2">

</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
</ul>
</div>
</nav>
PHP and HTML are completly different languages. With PHP you are generating HTML content. You are not including "the result" of nav.html, but the code.
I have the following head on my html file, but it seems like there's something wrong, because I'm trying to use scrollspy and navbar collapse and neither of them will work

I don't see anything wrong here... Can anyone help me? Thanks!
Bootstrap should be loading/working properly with the code you posted above. The problem is that you wrote date-toggle instead of data-toggle. Test the code below to make sure it works:
<nav class="navbar navbar-expand-lg navbar-light bg-custom fixed-top">
<div class="container-fluid">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<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>
</ul>
</div>
</div>
</nav>

I'm sorry... but your code is really terrible! Same ID twice, </div> never open, text without tag... really terrible! (^_^;)
I do not know where to start... maybe it's better if you read the bootstrap documentation http://getbootstrap.com/docs/4.1/getting-started/introduction/.
Now your menu works (I cleaned your HTML as best as I could), but you have to use HTML&CSS better because as it is, it is not a good work, sorry.
BTW, hope it helps you to improve your web designer techniques.
Cheers :)

Now all of a sudden it stopped working and I wonder why..
