# OAuth Buttons UI Redesign - Modern & Accessible
|
||||
|
||||
## Overview
|
||||
The OAuth authentication buttons have been completely redesigned to provide a modern, branded, and accessible user experience with professional styling that follows platform guidelines.
|
||||
|
||||
## Key Features Implemented
|
||||
|
||||
### 1. **Proper Brand Logos & Colors**
|
||||
Each OAuth provider button uses:
|
||||
- **Google**: Official Google Blue (#4285F4) with proper logo SVG
|
||||
- **GitHub**: GitHub Black with official Octocat SVG
|
||||
- **Facebook**: Official Facebook Blue (#1877F2) with proper logo SVG
|
||||
- **Discord**: Official Discord Purple (#5865F2) with proper logo SVG
|
||||
|
||||
### 2. **Modern Design Elements**
|
||||
|
||||
#### Rounded Corners
|
||||
- 11px rounded corners (`rounded-xl`) for a modern, softer appearance
|
||||
- Consistent with contemporary design standards
|
||||
|
||||
#### Button Layout
|
||||
- Full-width responsive buttons for better mobile experience
|
||||
- Consistent padding: `px-4 py-3`
|
||||
- Clear spacing between buttons: `space-y-2.5`
|
||||
- Proper icon alignment with text
|
||||
|
||||
#### Brand Logo Placement
|
||||
- SVG logos properly sized (5x5) and centered
|
||||
- Proper color rendering using brand colors
|
||||
- Clear visual distinction between providers
|
||||
|
||||
### 3. **Interaction States**
|
||||
|
||||
#### Hover State
|
||||
- Subtle border color change matching provider brand
|
||||
- Shadow enhancement: `hover:shadow-md`
|
||||
- Smooth transition: `transition-all duration-200`
|
||||
- Provider-specific hover colors:
|
||||
- Google: Blue (#4285F4)
|
||||
- GitHub: Black
|
||||
- Facebook: Blue (#1877F2)
|
||||
- Discord: Purple (#5865F2)
|
||||
|
||||
#### Active/Click State
|
||||
- Scale animation: `active:scale-95` for tactile feedback
|
||||
- Visual confirmation of interaction
|
||||
|
||||
#### Loading State
|
||||
- Spinning loader icon (⟳) appears on the right side
|
||||
- Only visible when `busy` state is active
|
||||
- Clear indication that authentication is in progress
|
||||
|
||||
#### Disabled State
|
||||
- Reduced opacity: `disabled:opacity-60`
|
||||
- Not-allowed cursor: `disabled:cursor-not-allowed`
|
||||
- Hover styles disabled: `disabled:hover:border-gray-200`
|
||||
- Prevents accidental re-submission
|
||||
|
||||
### 4. **Dark Mode Support**
|
||||
|
||||
Complete dark mode styling:
|
||||
- Light backgrounds: `dark:bg-slate-800`
|
||||
- Light text: `dark:text-gray-200`
|
||||
- Dark borders: `dark:border-slate-700`
|
||||
- Dark hover states: `dark:hover:border-[color]`
|
||||
- Smooth color transitions in both themes
|
||||
|
||||
### 5. **Accessibility Features**
|
||||
|
||||
#### ARIA Labels
|
||||
- `aria-label` attribute on each button for screen readers
|
||||
- Clear provider identification for assistive technologies
|
||||
|
||||
#### Semantic HTML
|
||||
- Proper button elements with meaningful titles
|
||||
- Clear text: "Continue with [Provider]"
|
||||
- No reliance on emoji alone
|
||||
|
||||
#### Keyboard Navigation
|
||||
- Full keyboard support for all buttons
|
||||
- Focus states inherited from base button styles
|
||||
- Tab navigation works correctly
|
||||
|
||||
#### Visual Clarity
|
||||
- Sufficient color contrast
|
||||
- Clear border indication
|
||||
- Text is not too small (text-sm = 14px)
|
||||
- Icons properly sized and aligned
|
||||
|
||||
### 6. **Responsive Design**
|
||||
|
||||
- Full-width buttons on all screen sizes
|
||||
- Proper spacing that adapts
|
||||
- Touch-friendly sizes (44px minimum touch target)
|
||||
