I am working on teaching myself web development, and I thought what a better way than to start my own personal web page.
I have run into an issue working with Bootstrap 4 and the navbar.
I can get the list, and the icon to show up when the window shrinks, but I can't get it to expand, or toggle collapse. I've even copied and pasted some code from the bootstrap documentation to see what I'm doing wrong and even then it doesn't work.
I've tried on both firefox and chrome, and on both, I am still unable to toggle the collapse with the icon button.
Here's the code:
<!DOCTYPE html>
<html lang="en">

ml-auto class in Bootstrap can be used to align navbar items to the right. The . ml-auto class automatically aligns elements to the right.
To create a collapsible navigation bar, use a button with class="navbar-toggler", data-toggle="collapse" and data-target="#thetarget" . Then wrap the navbar content (links, etc) inside a div element with class="collapse navbar-collapse" , followed by an id that matches the data-target of the button: "thetarget".
For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don't add any .navbar-expand class.
To slightly increase navbar height: add py-3 class to it. To increase its height a bit more: add py-5 class to your navbar. To decrease navbar height: add py-0 class to your navbar.
Although you've imported the Bootstrap CSS, you've neglected to import the required JavaScript.
Importing Bootstrap's JavaScript and the required dependencies (jQuery and Popper.JS) will cause your navigation to toggle correctly.
