Theme development

Hello,

I'm new to Drupal and developing a theme for a site on Drupal 8. I want to add a preprocess hook to my THEME.theme file that looks up taxonomy terms for nodes.

Hi,

Any module available for adding CSS Class to form fields (in Edit Mode) ? I found field_formatter_class, fences, semantic_fields but only working for Display (View Mode).

I do NOT want to play with theme functions which are hard-coded and not user-friendly for clients.

Hi,

I would like to get the domain url to my website in the mail template (use with a contact form).

I create a plugin to manage my mail system.

But I get nothing

Have you an idea ?
Thanks
