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.

The Four Controls

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 :focus-visible (not :focus) for better UX

4. Pause Animations
– Reduces motion for vestibular disorders
– Auto-detects OS prefers-reduced-motion preference
– Mirrors what the OS setting does

How It Works

Self-hosted CSS and JavaScript loaded from your site
Preferences saved in localStorage for returning visitors
Reduced-motion support based on the visitor’s operating system preference
Fixed-position toolbar trigger that stays available across the site
