Post installation

In my subtheme, I want to override the layout builder's CSS library, I tried the following :

libraries-override:
  layout_builder/twocol_section:
    css:
      theme:
        layouts/twocol_section/twocol_section.css: css/layout_builder/layouts/twocol_section/twocol_section.css
  layout_builder/threecol_section:
    css:
      theme:
        layouts/threecol_section/threecol_section.css: css/layout_builder/layouts/threecol_section/threecol_section.css

but (after clearing the cache) that didn't work.

Hello. I have an error that I still can't fix with the web form module, After fully installing the librarys and module, When creating a new web form, I get a text formatting error message.
I want to know is there any solution where I can create forms with drupal 10? I don't need it to be too complicated, but it just needs to be more customizable than the default contact module.
I know there's probably a problem with my modular webform installation because I don't have composer. But I have no other choice, I really can't change hosting right now.

In a Drupal 10 site (converted from Drupal 7), a content type has an image field that allows multiple uploads and a text field also allowing multiple values, which are used as captions for the images uploaded by the previous image field.

They are now displayed in this order:

• Image 1
• Image 2
• Image 3
• ...
• Caption 1
• Caption 2
• Caption 3
• ....

I want to display them in this order:

I want to turn a Drupal menu with a many links and sub links into a left sidebar accordion menu. An example is on the OPM website here in the left sidebar. 

I cannot make cron run on my D10 site. I'm not sure this is relevant, but the site was migrated from a Drupal 7 site.

In the status report, it says cron has not run since the site was created ('4 days 5 hours ago').

If I try to run it manually by clicking on the link provided on /admin/config/system/cron, Drupal loads a completely blank page, except for the message "The website encountered an unexpected error. Try again later."

I managed to install D 10.2.5 using the standard method on a shared linux hosting. Everything seems to be going well, but there are two small details that make me say I didn't do everything right.

- The "/update.php" page has no layout (simple text appears)

- On the same page, the "continue" link still shows the path to the "/web" subdirectory:
