Theming

The widget ships with a set of built-in theme presets. The active theme can be set via the dashboard, via a data-theme attribute on the container element, or driven dynamically from your page.

Setting a theme

Via the container element — set data-theme on the <div id="comments"> element:

<div
  id="comments"
  data-site-id="YOUR_SITE_ID"
  data-page-id="YOUR_PAGE_ID"
  data-theme="dark"
></div>

Via the dashboard — open Sites, select Configure, then choose your site and theme in the preview. The widget uses the saved setting on load.

Priority order:

data-theme on the container element (non-auto value)
Theme set in the dashboard for the site
auto (system preference)

The `auto` theme

When data-theme is auto or omitted, the widget follows the site’s dashboard setting. If that setting is also automatic, it follows the reader’s system light or dark preference.

Dynamic theme switching

The widget watches the container element for data-theme attribute changes using a MutationObserver. When the attribute changes, the widget updates its appearance immediately — no reload required.

// Toggle theme from your own page code
const container = document.getElementById('comments')
container.dataset.theme = 'dark'

Setting data-theme back to auto (or removing it) causes the widget to fall back to the dashboard-configured theme.
