Theming

Light, dark and system themes with coordinated semantic tokens.

Overview

Set data-xsh-theme=light|dark|auto. For runtime updates use Xshna.set(root,{theme:"dark"}); theme changes affect the scoped root only.

Semantic surface

Theme-aware colors.

Token-based styling

Example markup

<div class="xsh-grid xsh-grid-2 xsh-gap-4">
 <div class="xsh-card"><h3 class="xsh-h3">Semantic surface</h3><p class="xsh-muted">Theme-aware colors.</p></div>
 <div class="xsh-card" data-xsh-elevation="raised"><h3 class="xsh-h3">Token-based styling</h3><button class="xsh-btn xsh-btn-primary">Action</button></div>
</div>

Production guidance

Check actual contrast when overriding colors. auto uses prefers-color-scheme.

Customize this component through --xsh-* CSS tokens, data-xsh-* configuration attributes and documented xsh-* utilities. Use the optional JavaScript distribution only when an interactive behavior is needed.

ENGINEERING AND INTEGRATION

Implementation details

Semantic structure

Use the documented Xshna classes with semantic HTML rather than replacing native elements unnecessarily.

Compose existing xsh- classes on the appropriate HTML element. Keep content order meaningful when CSS is disabled.

Interactive behavior

Verify focus order, disabled behavior and descriptive labels for interactive patterns.

Load xshna.min.js only if the documented interaction needs it. Your application remains responsible for data, persistence and business rules.

Responsive and localization

Test narrow containers, long translations and user-defined text sizes.

Test 320px-wide viewports, container-constrained instances, keyboard zoom, longer translations and right-to-left text where relevant.

Theme and customization

Use --xsh-* CSS variables for theme values and data-xsh-design / data-xsh-density on the xsh-app root.

Prefer design tokens over hard-coded overrides so components remain coherent across personalities.

ACCEPTANCE CHECKLIST

What to verify before shipping

Confirm every documented class used by the feature exists in the release CSS.
Navigate controls using Tab, Shift+Tab, Enter, Space and Escape where appropriate.
Test with reduced motion, high contrast, 200% text zoom and a narrow mobile viewport.
Verify disabled, loading, empty, error and long-content states where relevant.
Check actual application behavior independently of the preview: these examples use illustrative data.
