navbar collapse does not collapse bootstrap - html

i'm fairly new to html, and imsimply trying to get the boostrap navbar to collapse but it doesn't work, the button shows up but it does not work, there are so many different questions on this forum concerning this problem but none have worked so far. i know there is a simple thing that i am missing but i can't seem to find where.
<nav class="navbar navbar-expand-lg navbar-dark">
<button class="navbar-toggler" 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>
<div class="collapse navbar-collapse navbar-dark" id="navbarNavAltMarkup">
<div class="navbar-nav">
<a class="nav-item nav-link active" href="#"><i class="fa fa-fw fa-home"></i> Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="bookreviews.html"><i style="font-size: 17px;" class="fa fa-fw fa-book-open"></i> Book Reviews</a>
<a class="nav-item nav-link" href="#"><i style="font-size: 17px" class="fa fa-fw fa-envelope"></i> Contact us</a>
<a class="nav-item nav-link" href="#">About us</a>
<a class="nav-item nav-link disabled" href="#">Pricings</a>
<a class="nav-item nav-link disabled" href="#"><i style="font-size: 17px;" class="fa fa-fw fa-user"></i> Login</a>
</div>
</div>
</nav>

FIXED: by just changing the class of my button to this ( as i was using another bootstrap version):
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>

Here You have example properly linked bootstrap 5 navigation, with working toggler.

You need include the scriptjs otherwise the nav collapse will not work

Bootstrap 5 navbar not collapsing

i have an issue with bootstrap 5 navbar toggle. It's not toggling.
Exactly same code with bootstrap 4 works fine.
I've already tried by some examples to remove navbar-toggler class from button and navbar-collapse class from navbar but it didn't work.
Workaround that I've used is to add onclick element to a button which would point to javascript which will add show class to navbar but I need to figure out why the native method doesn't work.
Tried on Firefox running on Fedora linux and Chrome running on Android 11 phone.

Change two things:
data-toggle="collapse" (Bootstrap 4) to data-bs-toggle="collapse" (Bootstrap 5)
data-target="#navbarNavAltMarkup" (Bootstrap 4) to data-bs-target="#navbarNavAltMarkup" (Bootstrap 5)
See the snippet below.

Bootstrap Hamburger Icon not aligning with Navbar-Brand

I'm trying to create a website using bootstrap and while using the navbar component, I'm facing an issue where in when the screen shrinks to the breakpoint I've set (which is lg) the hamburger icon's alignment gets disrupted as seen below.
Can someone please let me know why this is happening and what is the best way to fix this issue? Thanks in advance

I'm also attaching a picture of the issue:
Your problem is you put your button outside of container
<div class="container">
<span class="navbar-brand fw-bold">John Doe</span>
</div>
<button class="navbar-toggler ms-auto" type="button" data-bs-toggle="collapse" data-bs-target="#ToggleMenu" aria-controls="ToggleMenu" aria-expanded="false" aria-label="toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
It needs to be like this
<div class="container">
<span class="navbar-brand fw-bold">John Doe</span>
<button class="navbar-toggler ms-auto" type="button" data-bs-toggle="collapse" data-bs-target="#ToggleMenu" aria-controls="ToggleMenu" aria-expanded="false" aria-label="toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
</div>
You can try this fix

Can you please check the below code? Hope it will work for you. You are using Bootstrap 4 and therefore you require data-target and data-toggle attributes for your button navbar-toggler because you have used data-bs-target and data-bs-toggle attributes in the button which are bootstrap 5 toggle attributes.
Please refer to this link: https://jsfiddle.net/yudizsolutions/1oc4n2mu/

Bootstrap Navigation Bar Alignment Issue with Burger Dropdown

I'm trying to create a navigation bar using Bootstrap.
I tried adding ml-auto to the button, but it didn't do anything.
I'm expecting the burger icon to be on the right but it's just right next to the logo.

You forgot to close the img tag in your logo. Close it and it will fix it.
Change it from
<img src="logo.png" width="300" height="60"
to
<img src="logo.png" width="300" height="60">
