I'm a very beginner in drupal and I just want to add a css file to my custom theme.
So I created a upjv.libraries.yml in themes/upjv and I added :
global-styling:
version: '8.4.4'
css:
theme:
css/styles-upjv.css: {}
And I have created a styles-upjv.css in themes/upjv/css. On my index page, my file isn't loaded and I don't know if it's because I created the file in a wrong place, if the content of my libraries.yml is correct. Can anyone help me on this little problem please ?
