The navbar responsive issue when I resize the browser width - html

Question

The Burger bar animation & nav tag doesn't work when I resize the browser width. But when I refresh the page it shows and works. So I need to refresh the page every time when I resize the window width to make it work.
I code with Bootstrap v5.2 and jQuery.I have struggled with this problem for a while. Please help me up.
Many Thanks.

Answer 1

The issue with your current code is because you only check the window widths when the page loads, not when it resizes.
That being said you can make the code much more simple by toggling a class on the button. You can then use CSS transitions to animate the state of the menu based on the #media rules.
The only thing that's required in JS to make this work is to remove the class from the burger when the screen resizes in order to hide the menu once more.
jQuery($ => {
$('#toggle-menu').on('click', e => {
$(e.currentTarget).toggleClass('menu-is-active')
});
});
$(window).on('resize', () => {
$('#toggle-menu').removeClass('menu-is-active');
});

Here's a working example in jsFiddle - it's easier to see the resize logic working here as you can drag the frames.
