Bootstrap brand image overlapping container below the nav bar - javascript

I am trying to include a 400 x 100 png logo as a Navbar Brand image in Bootstrap 5. However, The logo appears to be a bit too big and even if I reduce the size of the logo, it still overlaps the black container and text input box underneath the Navbar in desktop view. In mobile devices, the logo and associated navbar overlaps even more. Also, the toggle button on the right is not aligned horizontally with the brand image on the left. I would like them to be on the same line. Attaching some screenshots for clarity. Can someone please help?
Desktop View
Mobile View
I would also want the brand image to be more aligned to the left in the mobile view. I am atatching the HTML code for review.

Remove the width height from image tag and use "img-fluid" class in image tag.
Or in mobile view you can use position absolute


Thanks for the suggestion provided by #Minhaj. I tweaked my code and it works fine now. I incorrectly placed the brand image in a separate div outside the navbar div. This is my new code:

How to shorten width of input field - Bootstrap v5 or CSS. keeping its responsiveness

I can't find a way to reduce the width of the input window in the code in the Jumbotron section. I can not see/find any code that controls the width of the input window. The code below is the code from Bootstrap v5. How do I shorten the width of the input window, keeping it centered and its responsiveness?

In Bootstrap the form-control class has 100% width. Remove the "form-control" class from this line:
<input type="email" id="email" class="form-control" placeholder="Your email" aria-label="Email" aria-describedby="basic-addon1">
Then you should be able to apply your own width to the input, either in the <style> block or with a different Bootstrap class.

Bootstrap multiple collapse togglers in same navbar

I'm just getting started trying to make a new bootstrap site and want to have the search bar as part of a seperate collapse toggle. Essentially on the right of the navbar I want the search bar toggle and then the menu toggle.
I have the following questions:
How can I alight the two buttons so they sit next to each other on the right side? One of them seems to sit in the middle right now and I'm not sure why.
Since I separated the form into a different DIV it seems to not align to the right side of the page anymore, it is indented a bit. Why is that?
I only one of the collapsed menus to be open at a time. E.g. if the search is open and I tap the menu toggle I want it to close the search and vice versa.
This is what I have so far. I know it's near default but I'm just getting started and am quite new to bootstrap.

1.: Simply add them to a separate node. The container has a flex-settings set, which align the child-nodes to fill 100% width with automatical spacing.
To overcome this, a new child node or different flex-settings are required.
<div class="container">
<a class="navbar-brand" href="#">Demo</a>
<div>
<a ...></a>
<a ...></a>
</div>
</div>
I mentioned this behavior some time ago here.
2.: The class .container adds margin to the left and right side and is flex-container, which varies by the break-point. Other classes like .row compensate this and use negative values to rearrange the content.
Bootstrap also offers example which will help you with the alignment in the navbar using ml-auto.
3.: If you want to open only one at a time, you should combine the buttons with the tab-handling. The accordion example might be the right choice. In the end it doesn't matter where you place the buttons or links, as long as the ids match with the content they have to display.

How can I make image slider responsive on every device?

Demo and full code like this :
https://codepen.io/positivethinking639/pen/WNbBjGX
I check on the mobile version(android and iphone) and tablet too, it's not responsive
How can I make it to be responsive on all device?

There are many double-quotes missing in the above code styles attribute
Added fixes to those
Added additional css to the image tag
Here is the working codepen:

So for your Javascript you could do something like this:
function sizeSlider(){
var w = window.innerWidth;
document.getElementById('mySlider').style.width = w
}
window.addEventListener("resize", sizeSlider); // set size on load
document.addEventListener('DOMContentLoaded', sizeSlider}); // set size on resize
And lest suppose your slider is named mySlider
<div id="mySlider">...</div>

Dynamic Bootstrap list with collapse is not working properly

I have created dynamic list using bootstrap and thymeleaf, list also contains collapse functionality which is not working properly, aria-expanded = "false" is not working, I browsed a lot but not any solution for dynamically created list using thymeleaf.
When the page loads all collapsible panel should be closed for that I used aria-expanded="false", but it is not working.
As the list comes into from it takes few clicks to achieve collapse.
Below there is the code and image.

Hello,
This is a template which I have modified .. outside flask when I am running this, this works fine ( without url_for ). But when I am trying to use within flask, the javascript files are not working .. please help me

Make sure your directory structure is modified for the root of you flask application, otherwise you're requesting js files that aren't there

You don't have to use url_for. Instead try:
<link type="text/css" src="{static/assets/css/core.min.css}" rel="stylesheet">
