I introduced a style file that defined the style of  .container , then ran it using parcel and found that the style didn"t work. 
I configured postcss:
{
  "modules": true,
  "plugins": {
    "autoprefixer": {
      "grid": true
    },
    "precss": {}
  }
}</script>
</body>
</html> after investigation, I found that the class name in my page is  .container , after parcel compilation and conversion of the css file, the original  .container  name was converted to . _ container_uquia_5 , because the class names are different, of course, the style is not effective, may I ask how to do this? 
it"s fine if I remove the configuration of postcss.
