[Vuejs]-External css sheet to override default Vuetify component style

Vuetify has built-in support for css-loader, so you can import * from 'css-library' (or whatever you’re trying to import).

Vuetify-specific (a-la-carte) components each have intuitive classes which you can modify in <style> or imported css, for example:

<template>
  <v-btn></v-btn>
</template>

<style>
  .v-btn {
    padding: 0;
  }
</style>
