Displaying CSS source on a webpage using Polymer 2.0 style modules for sharing styles

I have implemented a style module using Polymer 2.0 (https://www.polymer-project.org/2.0/docs/devguide/style-shadow-dom#style-modules).

The styles are functioning properly in Firefox, but in Chrome, the CSS content is displaying as jumbled characters on the webpage. How can I resolve this issue specifically for Chrome? Thank you in advance.

My code snippet:

lbw-css-styles.html

<dom-module id="lbw-css-styles">
  <template>
    <style>
    :root {
    background-color:green;
...
    </style>
  </template>
</dom-module>

page-test.html

<link rel="import" href="bower_components/polymer/polymer.html">
<link rel="import" href="bower_components/polymer/polymer-element.html">
<link rel="import" href="lbw-css-styles.html">

<dom-module id="page-test">
  <template>
     <style include="lbw-css-styles">
...
     </style>
  </template>

  <script>
    Polymer({
      is: 'page-test',
  </script>
</dom-module>

Answer №1

Solved the problem! I discovered that my CSS was using a ":root" selector which is no longer supported in Polymer 2.0. By removing this deprecated selector, the issue was fixed.
