[neuling] Probleme beim Hinzufügen eines Skripts, um CSS-Werte basierend auf Bedingungen dynamisch zu ändern

[cpradio]

That isn’t how you’d do it there. To do it there, you’d have to do something like

<script type="text/discourse-plugin" version="0.4">
api.onPageChange((url, title) => {
  alert('test');
});
</script>

My original post was from a plugin perspective.
