18, 6,2025 Updated Main Stylesheet (/assets/css/main.css) The primary CSS file was revised to improve the overall appearance and maintainability of the website. Changes included modernizing layout components, refining color schemes, improving responsiveness across devices, and aligning styles with updated design guidelines. Redundant and unused classes were removed, and comments were added for better readability and developer collaboration.

Upgraded Bootstrap Framework to Version 5.0 The website's frontend framework was upgraded from an earlier version of Bootstrap to Bootstrap 5.0. This update brings several enhancements, including a cleaner grid system, dropped dependency on jQuery, improved utility classes, and enhanced accessibility features. Existing components and layout structures were updated accordingly to ensure compatibility and a seamless transition.

Fixed SQL Injection Vulnerabilities Several security patches were implemented to mitigate SQL injection vulnerabilities. Input fields were reviewed and updated with strict validation and sanitation. Parameterized queries and prepared statements were used in all database interactions to prevent malicious data manipulation, enhancing the overall security posture of the application.

Implemented Lazy Loading for Images To improve page load performance, lazy loading was introduced for image elements. This optimization ensures that images are loaded only when they enter the user’s viewport, reducing initial page load time, saving bandwidth, and enhancing the user experience on slower networks or mobile devices.

Removed Deprecated jQuery Functions from script.js Legacy jQuery methods that were deprecated in recent versions were identified and removed from the script.js file. Modern JavaScript alternatives or supported jQuery methods were implemented in their place. This cleanup helps future-proof the codebase, reduces potential errors, and improves compatibility with 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.
