Having trouble with the following transformation:

<style type="text/css">
    @media (prefers-color-scheme: dark) {

      .textPrimary {
        color: #E2E2E2 !important;
      }

      @media (max-width: 630px) {

        body,
        .footerContainer {
          background-color: #1E1E1E !important;
        }
      }
    }
  </style>
