# Header Component Fix Summary
## Issues Identified and Fixed
### 1. Height Consistency
**Issue**: Inconsistent height definitions between Tailwind classes (`h-14` on mobile, `h-16` on larger screens) and CSS (`height: 4rem`).
**Fix**: Standardized to `h-16` (4rem/64px) across all screen sizes for both Tailwind classes and CSS.
### 2. Padding Consistency
**Issue**: Header content padding was defined with Tailwind classes (`px-3 sm:px-4 lg:px-8`) but not reflected in CSS.
**Fix**: Updated CSS to match the corrected Tailwind classes:
- Mobile: 1rem (px-4)
- Small screens (sm): 1.5rem (px-6)
- Large screens (lg): 2rem (px-8)
### 3. Responsive Breakpoint Alignment
**Issue**: Mismatch between Tailwind's `lg:` breakpoint (1024px) and CSS media query (767px).
**Fix**: Updated CSS media queries to use 1023px max-width to match Tailwind's lg breakpoint.
### 4. Z-Index Standardization
**Issue**: Header was using `z-50` which could conflict with the Sidebar's z-index.
**Fix**:
- Header: z-index 40 (var(--z-40))
- Sidebar: z-index 50 (var(--z-50)) on mobile to ensure it appears above the header
### 5. Spacing Standardization
**Issue**: Inconsistent spacing between elements on different screen sizes.
**Fix**: Standardized spacing values:
- Logo section: `space-x-3` (consistent across screen sizes)
- User profile section: `space-x-4` (consistent across screen sizes)
### 6. Component Structure Improvements
**Issue**: Minor inconsistencies in component structure.
**Fix**:
- Standardized button sizes and padding
- Consistent avatar sizes
- Unified text sizes and styling
- Improved mobile menu button sizing
