A PHP package for ensuring web applications meet accessibility standards, particularly for color contrast.

Features

• Color Contrast Checking: Determine if text colors have sufficient contrast against background colors
• Accessible Text Color Generation: Generate accessible text colors based on background colors
• Color Format Support: Support for hex, Tailwind CSS, rgb(), and hsl() color formats.
• User Accessibility Settings: Manage user preferences for accessibility features

Installation

You can install the package via Composer:

composer require artisanpack-ui/accessibility

For detailed installation instructions, including Laravel integration, see the Getting Started Guide.

Usage

Here is a practical, real-world example of how to use the package to create an accessible button component in Laravel.

Creating an Accessible Button Component

1. Create a new Blade component:

php artisan make:component Button

2. Modify the component class:

In app/View/Components/Button.php, we'll accept a background color and automatically determine the correct text color.

// app/View/Components/Button.php

namespace App\View\Components;

use Illuminate\View\Component;

class Button extends Component
{
    public string $bgColor;
    public string $textColor;

    public function __construct(string $bgColor = '#3b82f6')
    {
        $this->bgColor = $bgColor;
        $this->textColor = a11yGetContrastColor($this->bgColor);
    }

    public function render()
    {
        return view('components.button');
    }
}

3. Update the component view:

In resources/views/components/button.blade.php, we'll apply the colors as inline styles.

// resources/views/components/button.blade.php

@props(['bgColor', 'textColor'])

<button {{ $attributes->merge(['class' => 'px-4 py-2 rounded']) }} style="background-color: {{ $bgColor }}; color: {{ $textColor }};">
    {{ $slot }}
</button>

4. Use the component in your views:

Now you can easily create accessible buttons with any background color.

<x-button>Click Me</x-button>

<x-button bg-color="#dc2626">Delete</x-button>

<x-button bg-color="rgb(16, 185, 129)">Success</x-button>
