Theme development

I'm trying to change Bootstrap colors, but it doesn't work. Here is the error message :

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 ?
