The first way is, write any stylesheet in
layout/default.vue. This way is very simple and good for small project. You won't need any another file.
and as alternative, you can make
style.css file in aseets folder and import it in
default.vue. Or, just make the file and load it in
The second way is, use
@nuxtjs/style-resources. I think this is not good way because this causes mess the project.
