THEMES / COLOUR MODE

Light theme

Choose an explicitly light palette for backgrounds, foregrounds, surfaces and native controls.

Activate on the page

Only one theme value is needed. Default is the standard palette; Mono is optional. Add data-palette to choose another colour family; other component settings keep their shared defaults.

<html lang="en" data-theme="light">
  <!-- Load reva.css in the head, then add your content. -->
</html>

This explicit value takes precedence over the device’s preferred colour mode. The documentation theme menu changes this document only; it does not persist across navigation. Fixed theme values inside individual demos remain local overrides.

The same component markup

No theme attributes are repeated on the card, actions, badge or alert.

    <h3>Your account</h3>
    <p>Surfaces, text, links and controls use this colour mode.</p>
    <p><span class="badge" data-variant="success">Active</span></p>
    <div class="row">
      <button type="button">Save changes</button>
      <button type="button" class="secondary">Cancel</button>
    </div>
  </article>
  <div class="alert" data-variant="warning">Warning: Verify your email address.</div>
</section>

Override one section

A nearer theme value changes this section while leaving its neighbours in the page mode.

A local colour mode

Other settings still inherit independently.

<section data-theme="dark">
  <article class="card">
    <h3>A local colour mode</h3>
    <p>Other settings still inherit independently.</p>
  </article>
</section>

Add glass independently

Load reva.glass.css after the core and add data-material="glass" to a parent. The theme remains light. Styled text controls retain their normal backing.

Inspect the light and dark palette tokens. Both modes use the same shape, density and component defaults.
