Theme development

I want to add a feature to my Drupal site that displays WhatsApp group links categorized by interests. What Drupal modules or methods are best for managing and displaying these links? How can I ensure the feature is user-friendly and secure?

After creating a sub-theme, and viewing the page source, are file paths still inherited from the parent, or do they use the name of your sub-theme?

For example, if the parent theme is named "silly-name", and you created a sub-theme named "better-name", are all the links all based on the sub-theme (A) or would they be a mix of the sub and parent (B)?

Example A (custom)

../themes/contrib/better-name/

Example B (mixed)

../themes/contrib/better-name/ and ../themes/contrib/silly-name/

Hi.

Not sure if it is the correct section here… if not, please move or advise…

I want to have a video poster in the file > video field. I have not yet been able to find a practicable solution. So i thought i can do this by simply adding the url for the poster image inside the <video> tag. But i don't know how to get the url value as a token working in twig. I am also not sure if the image would be from the actual node. Maybe this apporach is not even working.

This is on a Drupal 10 site, and I guess that a Drupal or module update went wrong?

Suddenly the variables in page-html.html.twig are empty for taxonomy pages.

Symptom: the taxonomy page title is not displayed.

This happens with an existing starterkit theme, but also with a brand new one created with

php php core/scripts/drupal generate-theme --name TestVarSetting --path themes/custom/ -n TestVarSetting

What I am trying to do is if the text "No front page content has been created yet. Follow the User Guide to start building your site." is on the front page replace it with my own template, that displays the same text but gives more information on how to create content as well as resources to get help. I am well aware that creating content and promoting it to the front page or creating a page--front.html.twig file will remove this text but that defeats the purpose.

I'ld like to create a dedicated sub-theme that looks like exactly like its parent, layout included. So I followed the blocks and regions inheritence instructions:
