I created my own Drupal 8 theme:
mytheme.info.yml:
name: My Theme
description: 'Drupal 8 Theme'
type: theme
base theme: bartik
core: '8.x'
mytheme.libraries.yml
global-styling:
version: 1.x
css:
theme:
css/layout.css: {}
css/style.css: {}
css/colors.css: {}
css/print.css: { media: print }
I am using "Seven" as admin theme.
When I edit a page (/node/x/edit) Seven theme is used.
Now I have to add some CSS the the edit form. How can I do this? style.css is only loaded on front end pages. Edit pages use seven theme and my theme CSS is ignored.
How can I add some CSS to admin pages or edit forms in Drupal 8?
