I use drupal 8, and Bootstrap theme.
I created a sub-theme.
I would like added one font that I downloaded, to use it in my sub-theme.
I read contradictory things to realize it. For example that it was enough to create a folder "font" in its sub-theme, and add the font in it, then add it in
mytheme.libraries.yml, or that it was necessary to place this font in the folder
vendor/ . I am a little lost.
How can it be done?
