1, 1,2025 Updated Styling in the Main Stylesheet The primary stylesheet, located at /assets/css/main.css, was updated to enhance the overall design and user experience. This involved making adjustments to the layout, colors, fonts, and spacing to ensure a more modern and cohesive look across the website. Specific changes could include refining padding and margins, updating hover effects, or modifying typography to improve readability.

Resolved SQL Injection Vulnerabilities Security issues related to SQL injection vulnerabilities were identified and resolved. This involved reviewing and sanitizing database queries to ensure that user inputs are properly validated and escaped. By implementing prepared statements and parameterized queries, the system is now protected against potential exploits where attackers could manipulate queries to gain unauthorized access or modify the database.

Improved Loading Performance Through Lazy Loading To enhance page speed and optimize resource usage, lazy loading was implemented for images. This means that images are now loaded only when they are about to appear in the user’s viewport, rather than loading all at once when the page is initially accessed. This change significantly reduces the initial page load time, leading to a smoother user experience, especially for content-heavy pages with numerous images.

Removed Deprecated jQuery Functions in script.js Outdated or deprecated jQuery functions in script.js were removed and replaced with modern alternatives. Since newer frameworks and browsers now support vanilla JavaScript for most functionalities, these updates reduced dependencies and improved code maintainability. This change also aligns the script with the updated Bootstrap 5 framework, which no longer relies on jQuery, ensuring smoother integration and better performance.
