Theme development

Hello, I wanted to uninstall the Views Bootstrap module and I have done so successfully.

However, when I look at my list of modules, I can still see it in the list. Therefore, I tried to uninstall again, but I am unable to uninstall it a second time as it is not in the "Uninstall" list of modules.

When I try to install the module again, it says that the module is already installed. What should I do?

Hello,

I'm following some tutorials on Drupal and sometimes it says to turn off certain modules. For instance, here I have to turn off the "Comment" module, which is in the "Core" section of Drupal. However, I am unable to turn it off. For some reason, I cannot modify any of my "Core" modules (it shows up in light gray and I'm unable to select or unselect them). Any reason why?

Thank you!!

I installed the Twig Tweak module on my site to render Views on the home page.

I want to make the display mode frontpage_tasks for the current user, his account, his stores and his groups.

{{ drupal_entity('user', user.id, 'frontpage_tasks') }}
{{ drupal_view('accueil_page_liste_des_taches_boutique', 'block_1') }}
{{ drupal_view('accueil_page_liste_des_taches_groupe', 'block_1') }}

Here is one of my Views :

Hello,

I just installed a Drupal sub-theme via CDN. Now, the first thing I'd like to do is to install a carousel on the front / home page.

I'm not sure how to do this..

I've looked at the official Bootstrap site (https://getbootstrap.com/docs/5.0/components/carousel/) and that leads me to 3 questions:

1) I have Drupal 9 and Bootstrap 3 installed. This website (link above) is for Bootstrap 5. Should I be referring to this website?

In the menu at the top left of my site, I have accordion menu.

I want to rotate the "+" icon when the accordion is open.

In the green buttons, at the top of the menu, I want to make a roration of the "^" icon when the accordion is open.

The rotation works, but the icons do the rotation, even though I didn't click on the accordion.

Why is it not working properly ? What is wrong with my CSS ?

I read the following on Drupal on Sub-Theming:

You should never modify any theme or sub-theme that is packaged and released from Drupal.org, such as Drupal Bootstrap. If you do, all changes you have made will be lost once that theme is updated. Instead, you should create a sub-theme from one of the provided starterkits (this is considered a best practice). Once you've done that, you can override CSS, templates, and theme processing.

My question is the following:
