About the xtal-match-media category

xtal-match-media: Published on webcomponents.org

<xtal-match-media>

Web component that watches for media matches and fires events when they happen.

This is similar to Polymer’s iron-media-query, but with no legacy dependencies. xtal-match-media can partake in Polymer’s powerful binding.

Other alternatives are also available (the more the merrier):

lit-media-query (webcomponents.org - Discuss & share web components)

  <p-d on="matches-media-query-changed" prop="textContent"></p-d>
  <div></div>
  <script type="module" src="https://unpkg.com/p-d.p-u@0.0.105/p-d.js?module"></script>
    <script type="module" src="https://unpkg.com/xtal-match-media@0.0.5/xtal-match-media.js?module"></script>
</div>
