addressbar | browser work just like a normal input | Frontend Framework library

So I have been experimenting with adding darkmode to my website and it has been going very well so far, I have a 0.3s ease transition for the theme change, so the change isn't very abrupt. I used this JS code to change the color of the address bar in chrome for mobile

I am trying to implement bigcommerce embedded checkout into my rails application. I followed this url to integrate embedded checkout into my local rails application. https://developer.bigcommerce.com/api-docs/storefronts/embedded-checkout/embedded-checkout-tutorial

But I have error message of "NotEmbeddableError: Unable to embed the iframe because the content could not be loaded." These are the steps I did.

1. I am using rails application locally. it is running as https://127.0.0.1:3000 (I've tried with localhost, but I can't create site using localhost: it says site name should not contain localhost string) I created local ssl key and certification and runs the application by rails s -b 'ssl://127.0.0.1:3000?key=127.0.0.1.key&cert=127.0.0.1.crt'

And I can access the local site by https://127.0.0.1:3000/ although it says 'Not Secure'

1. I followed the embedded checkout url APIs and able to produce the redirect_urls for example:

I apologize for the vague title, but my issue is fairly specific. I'm currently converting our site to use Bootstrap, and I've come across a small thing that bugs me with the header (jumbotron). When viewed on mobile, or with a xsmall/small screen size, the words "Service" and "Agency" will force down to the next line and display underneath our tree logo (shown in pictures)

EDIT: Forgot to mention, I cannot just simply split the tree logo and words into two different columns, as this forces them to appear on opposite ends of the screen when viewed on desktop.

Small Screen

XSmall Screen

Desktop Screen

Instead, I'd like for the words "Human", "Service", and "Agency" all to display stacked on top of one another, next to the tree, when viewed on small or xsmall screens. Any ideas on how to approach this?

HTML:

So my end goal is to detect when the user has pressed the left mouse button on a webpage (any element like a button, image and so on). With this I'd run some javascript to get the proper html data I need based on where the user has clicked.

Without taking it any further, I'm already stuck at the first part where my browser control doesn't seem to fire any events related to the mouse. However it does seem to provide handlers like MouseDown, MouseEnter, MouseClick and so on but doesn't seem to fire any of them.

I've tried setting up a simple WinForms test project with a textbox control and a button. The browser is added manually like so:

How to keep original URL in addressbar after RewriteRule

This is a similar question on stackoverflow, but even with the answers there I can not solve this in my case.

I have this dynamic image:

If you open it, you can see that the htaccess is working and there is a redirect. I don't want the redirect. I want that the url is not to be changed.

Goal

Login a user in a Laravel package.

Problem

Pressing the login button redirects to the startpage and in the console i get a 302 status code. Thats the route of the login button: Login. It is defined in web.php as follows: Route::get('login', [LoginController::class, 'login'])->name('login'). The same happens when i try it in in the addressbar with: 127.0.0.1:8000/login.

Description

It's my first try with laravel packaged development. Therefore I created a new Laravel app with Laravel 8. With php artisan ui bootstrap --auth i created the authentication scaffolding and now tried to make it a laravel package. I followed this instructions.
You can find the whole branch of the project here.
Thanks in advance for your time.
Thats the stucture of the package until now:

Routes

When you visit this web site https://bugs.stringmanolo.ga/index.html, while navigating around the main.js file is calling a method from ff.js file to cache a good amount of the resources. So next time you land to the web the files are directly taken from your browser cache without make any request.

This means if you visited my website before, you can load it again without internet conection.

The problem is, this only works if you directly time the index.html file in the addressbar. Lame.

Thid url dosn't work loaded offline. https://bugs.stringmanolo.ga

This other one works fine. https://bugs.stringmanolo.ga/index.html

How can i make the web cache also loads the index.html when the base url is requested?

Is there a way of making a flutter web app enter fullscreen mode (hide addressbar, tabsbar and taskbar)? Or is there a way of programmatically pressing F11?

I've tried...

I am trying to simulate Google's behavior where the user types something on the address bar of the browser and the Django server checks for any exact matches in the database. If so, a detailview of the object is rendered. If not an exact match, then a list of matches on substrings are rendered with ListView.

This behavior works fine when the user types into a search form. For instance, when the user just types the letter 'j' in the search form and hits submit, the Django server matches on 3 objects in the data base 'Django, Java, node.js' and renders this list through ListView. If there is an exact match, say the user typed 'java', then the Django server renders details about the object 'java' in a Detail view.

However, I could not figure out how to derive the same behavior when applied to what the user types on the address bar of the browser. If the user happens to type just the exact spelling of an item in the db, the details of the item is rendered, otherwise we get a 404 error.

The relevant segments of the html form, urls.py, and views.py are displayed below
