I'm testing creating new themes in Drupal 8 and I'd like to know the very minimum it takes to create one that can be enabled. I'm not worried about any actual styling yet.

I've created a theme folder in themes called uktheme and I currently have a uktheme.info.yml file in that folder.

the contents of that file are

name: UK Theme
type: theme
description: 'Test theme'
package: Core

regions:
  header: Header
  primary_menu: 'Primary Menu'
  feature: 'Feature'
  content: 'Content'
  page_bottom: 'Page Bottom'
  footer_first: 'Footer first'
  footer_second: 'Footer second'
  footer_third: 'Footer third'

However I receive

The website encountered an unexpected error. Please try again later.

when attempting to go into the appearance settings. I do not believe it's my folder structure and location because I successfully created another theme copying the content of Bartik.

Perhaps you've missed core.
Required params in *.info.yml are:
name
description
type
core
regions:content

Also you can check your *.info.yml for using tabs instead of spaces:

Tabs are NOT allowed, use spaces ONLY.
You MUST indent your properties and lists with 1 or more spaces.

See more in official docs: https://www.drupal.org/theme-guide/8/defining-a-theme

There is a space in your name, that should be wrapped in quotes: name: 'UK Theme'. That space could be causing an error as it produces invalid code.

And also I am pretty sure your theme does not ship with core ;)

  • Hmm, it seems spaces are allowed in YAML (I always thought it was more JSON like). This probably does not solve the issue... – Neograph734 Apr 12 '16 at 14:27
