SlimBar adds a compact accessibility toolbar to the front end of your WordPress site. Visitors can switch contrast modes, adjust font size, highlight keyboard focus, and pause animations. The plugin keeps its assets self-hosted and stores user preferences locally in the browser.
<h4>The Four Controls</h4>
1. High Contrast Toggle 
– Three modes: Off → High-contrast dark → High-contrast light 
– WCAG AAA compliant color ratios (7:1+) 
– Persistent across page loads
2. Font Size Scaler 
– Four discrete steps: 100%, 115%, 130%, 150% 
– Scales rem-based typography 
– No slider confusion
3. Keyboard Focus Outline 
– Highly visible 3px outline with offset 
– WCAG 2.2 AA compliant by default 
– Uses <code>:focus-visible</code> (not <code>:focus</code>) for better UX
4. Pause Animations 
– Reduces motion for vestibular disorders 
– Auto-detects OS <code>prefers-reduced-motion</code> preference 
– Mirrors what the OS setting does
<h4>How It Works</h4>
<ul>
<li>Self-hosted CSS and JavaScript loaded from your site</li>
<li>Preferences saved in <code>localStorage</code> for returning visitors</li>
<li>Reduced-motion support based on the visitor’s operating system preference</li>
<li>Fixed-position toolbar trigger that stays available across the site</li>
</ul>
<h4>Features</h4>
<ul>
<li>Four Essential Controls: Contrast, font scaling, focus outline, and animation pause</li>
<li>Preference Persistence: All settings saved to localStorage and survive page reloads</li>
<li>OS Integration: Automatically respects <code>prefers-reduced-motion</code> on first load</li>
<li>WCAG 2.2 AA Compliant: The toolbar itself meets accessibility standards</li>
<li>RTL Support: Full right-to-left language support</li>
<li>No Inline Event Handlers: Uses JavaScript event listeners instead of inline <code>onclick</code> attributes</li>
<li>Theme Compatible: Designed to work with WordPress themes and page builders</li>
<li>Admin Customization: Position, colors, feature toggles, and exclusions</li>
<li>Mobile Optimized: Responsive design with proper touch targets (48×48px)</li>
</ul>
<h4>What This Plugin Does NOT Do</h4>
<ul>
<li>NOT a full-site accessibility scanner</li>
<li>NOT an ADA/EAA compliance guarantee</li>
<li>NOT a text-to-speech or screen reader</li>
<li>NOT a dyslexia font tool</li>
<li>NOT connected to any remote service</li>
<li>NOT supported on Internet Explorer 11</li>
</ul>

What data is sent and when: 
– When the widget is loaded, the browser requests the script file from the CDN. No personal data is sent by the plugin to AxesWeb. The plugin does not add cookies or tracking. 
– When the optional accessibility feedback form is enabled, submissions are sent to your WordPress site via admin-ajax.php using a nonce-protected action. Emails are dispatched by your site to the recipient you configure. No data is sent to AxesWeb for this feature.
