CSS styles not working while included in .info.yml file For some reason my theme can't find css/style.css in Drupal 8.

This is the .info.yml:

name: Adminimal
type: theme
description: Drupal Administration Simplified.
# version: VERSION
# core: 8.x
base theme: seven

# Include CSS.
 stylesheets:
  all:
   - css/style.css

# Information added by Drupal.org packaging script on 2014-10-23
version: '8.x-1.x-dev'
core: '8.x'
project: 'adminimal_theme'
datestamp: 1414059738


This is how the folders look like:

Theme/adminimal.info.yml
Theme/css/style.css


The css in the style.css file:

html{
    background-color: blue !important;
}


It doesn't even show up in the styles section in my Google Chrome console so I think it doesn't find the file but why?

And about jQuery in Drupal, I can't manage to get this working: https://www.drupal.org/node/1541860 To work with: //ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js How should I do this?
