title: Angular 1.x template-best practice to use CSS styles
body: <p>I'm a web developer, not an CSS expert. We recently started using Angular and I'm wondering what is the best practice applying styles in Angular templates.
  Discussion we have at work is whether to use external CSS files or internal style tags. We do not have too many templates and each template mostly has its own unique styles. We are debating between external CSS files and/or internal styles.
  Couls someone provide an expert opinion on this subject.</p>
