Theme development

How can I change the count number that is produced by the Statistics module to be displayed as a formatted number. So instead of "123456" display "123,456"?

Hello Drupal Community!

I'm (obviously) new to Drupal and have seen this question repeated a hundred times in the forums, but am unable to find clarity. It's likely I'm misunderstanding how to add CSS to an existing theme. This is on a local server so I'm seeking understanding rather than someone to fix this for me. From my understanding to add CSS/JS:

Add source to /themes/selected_theme/selected_theme.libraries.yml

Hey there!

I was using Drupal since version 5 and 6, 7 years ago. A lot of things have changed and now I'm interested on doing something with Drupal 7. As far as I have seen many sites now accommodate things dinamically either if it's for Desktop or Mobile. For example, Menu changes from a bar (on the desktop) to a clickable square (on mobile).

Do any one know Matrimonial Drupal theme to develop a Matrimonial Website like others can register and add their profiles etc?

Found this theme but its not relased yet.

Thanks for your Support in Advance.

I am building Bootstrap-based theme and I have created one block that renders the main menu.

return array(
       '#markup' => drupal_render($menu),
       '#theme' => "menu__mobile",
     );

As seen above I state that the theme file should be menu--mobile.html.twig. If I state no "#theme" variable it uses the default menu--main.html.twig.

I am about to build a site where the secondary links will be in vertical tabs on the side. (Please excuse the layout at the moment). Site will be shifting to Drupal, can not share the staging server URL right-now.

I want to be able to create the menus dynamically as the user adds more content.
