Post installation

I don't know Twig but I have a small question for those who do.

I have added a new region in page.html.twig:

{{ page.phone_message }}

I want this new region to contain all CSS classes of the Content region:

region--content grid-full layout--pass--content-medium

I have tried this, which didn't work (the block just vanished):

Does anyone know of a theme like TheDropTimes, it appears to be a custom sub-theme of Olivero (Drupal 10 default)?

Mainly, I'd like to replicate the Top Spotlight block, a 3 column layout below, and a similar top Nav bar.

I haven't been able to find any recent information on possible causes or solutions to this error that pops up when trying to login to my new Drupal 10 site as the admin account.

I'm working on this Drupal 10.x site with content types Author and Book.

I have a view which displays all kinds of information about each author.  That works fine.

I want the user to be able to select the author of interest.

I set up a Taxonomy vocabulary of Author Name and added that field as an entity reference to my content type Author.  I added an exposed filter to the Author Information view using the taxonomy of Author Name.  This works exactly as I want it to.

However, I sense that there's a problem with this design.

In example.info.yml I have declared a new region:

phone_message: 'Phone Message'

In /templates/layout/page.html.twig I have added a new region named

{{ page.phone_message }}

Drupal 10.2.4 core without any core customizations.

I have created a simple view with the filter criteria published=yes and content_type=x and the sort criteria global:random but the randomness just doesn't work.

For example, I can run the website on a web browser with no history and caching at all (all browser history and caching from all time is cleared after exiting the browser) and I will still get the exact same results for the view.
