7, 12,2025 Main Stylesheet Revamped (/assets/css/main.css) The core stylesheet of the website underwent a comprehensive revision to enhance both visual presentation and code maintainability. Key improvements include:

Modernized Layout Components: Reorganized structural styles to align with contemporary design standards.

Refined Color Scheme: Updated color palette for better visual harmony and accessibility.

Responsive Enhancements: Optimized styling to ensure consistent behavior and appearance across a wide range of devices and screen sizes.

Code Cleanup: Removed unused or redundant CSS classes and selectors.

Improved Readability: Introduced meaningful comments and organized code blocks to facilitate easier collaboration and maintenance by developers.

Bootstrap Framework Upgraded to Version 5.0 The website's front-end framework was upgraded from a previous Bootstrap version to Bootstrap 5.0, resulting in multiple performance and usability benefits:

Cleaner Grid System: Simplified layout structures with enhanced flexibility.

Removal of jQuery Dependency: Reduced load time and improved compatibility by eliminating the need for jQuery.

Expanded Utility Classes: Greater customization with minimal code.

Accessibility Enhancements: Improved support for screen readers and keyboard navigation. All existing components and layout elements were reviewed and updated to ensure full compatibility with the new version.

Resolved SQL Injection Vulnerabilities Critical security measures were implemented to protect the application against SQL injection attacks:

Input Validation & Sanitization: All user input fields were thoroughly reviewed and updated with strict validation rules.

Use of Prepared Statements: Database interactions were rewritten to use parameterized queries, preventing unauthorized access or manipulation. These changes significantly strengthen the website’s defense against common web vulnerabilities.

Enabled Lazy Loading for Images To improve performance and user experience, lazy loading was activated for all image elements:

Optimized Page Load Time: Images now load only when they enter the user’s visible area (viewport).

Reduced Bandwidth Usage: Prevents unnecessary image loading, especially on slower connections.

Improved Mobile Experience: Faster initial rendering for users on mobile or limited networks.

Deprecated jQuery Functions Removed from script.js Outdated jQuery methods were identified and replaced in the site’s custom JavaScript file (script.js):

Modern JavaScript Alternatives Used: Where possible, native JavaScript or current jQuery functions were implemented to maintain functionality.

Cleaner, More Reliable Codebase: This update eliminates potential compatibility issues and reduces reliance on legacy code.

Improved Browser Support: Ensures smoother operation across all modern browsers.

Upgraded Bootstrap Framework to Version 5.0: The project has been migrated from an earlier version of Bootstrap to version 5.0. This upgrade provides a more modern component library, improved grid system, better accessibility support, and removes the dependency on jQuery. All associated layout and component classes were updated to comply with Bootstrap 5’s syntax and conventions.

Patched SQL Injection Vulnerability: A critical security issue related to SQL injection was identified and resolved. Input validation and sanitization procedures were improved, and prepared statements were implemented where user input interacts with the database. This helps prevent malicious input from compromising the system or accessing sensitive data.

Implemented Lazy Loading for Images: Image elements throughout the site were updated to use lazy loading. This means images now load only when they are about to appear in the user’s viewport, reducing initial page load time and improving overall site performance—especially on slower network connections.

Removed Deprecated jQuery Functions from script.js: Several outdated jQuery methods were removed or replaced with modern JavaScript alternatives. This improves code reliability, aligns with current best practices, and contributes to better browser compatibility. The codebase is now cleaner and more efficient, with reduced reliance on legacy scripts.
