title: Importing CSS with webpacker in Rails 6
body: <p>I use webpacker with Rails and am installing taildwindcss right now. Their <a href="https://tailwindcss.com/docs/installation/" rel="noreferrer">installation guide</a> says to use an <code>@import</code> method if I'm using <code>postcss-import</code>. I must say I get confused whenever I have to import CSS to Rails with webpacker, so I have a few questions:</p>
  
  <p>1) The <code>@import</code> method from the docs - is it a JavaScript or CSS import method?</p>
  
  <p>2) If it's a CSS method, why do I have to paste it inside javascript folder (e.g. <code>javascript/stylesheets</code>? I tried to put it inside the application.css file and it doesn't work. I assume it is somehow related to the fact that it's using PostCSS and package was installed via yarn?</p>
  
  <p>3) If the above is true, does it mean that I have to import every CSS package that way if it's installed via yarn? </p>
