|
|
|
|
## Overview
|
|
The login page has been enhanced with comprehensive mobile-responsive CSS to provide an optimal user experience across all device types and screen sizes.
|
|
|
|
## Mobile-Responsive Features Added
|
|
|
|
### 1. **Responsive Breakpoints**
|
|
- **Tablet (≤768px)**: Column layout, optimized logo and form sizing
|
|
- **Mobile (≤480px)**: Enhanced touch targets, better spacing
|
|
- **Small Mobile (≤320px)**: Minimal padding, compact design
|
|
- **Landscape (height ≤500px)**: Horizontal layout for landscape phones
|
|
|
|
### 2. **Layout Adaptations**
|
|
|
|
#### Desktop (>768px)
|
|
- Side-by-side logo and form layout
|
|

|
|
|
|
#### Tablet (≤768px)
|
|

|
|

|
|
|
|
### 3. **Touch Optimizations**

|
|

|
|

### 5. **Performance Considerations**

- Optimized image rendering for retina displays
|
|

|
### Flexible Layout

|
|
}
|
|
```
|
|
|
|
### Touch-Friendly Inputs
|
|
```css
|
|
.form-container input {
|
|
padding: 12px;
|
|
font-size: 16px; /* Prevents iOS zoom */
|

}
|
|
```
|
|
|
|
### Landscape Optimization
|
|
```css
|
|
@media screen and (max-height: 500px) and (orientation: landscape) {
|
|
.login-page {
|
|
flex-direction: row; /* Back to horizontal */
