CSS and JavaScript Enhancements for Optimized Performance and Maintainability

[UjjawalPrabhat]

Hello! I've reviewed the HTML and CSS code for the "Year Progress" page, and I noticed a few areas where enhancements could improve performance, accessibility, and maintainability. Here are some suggestions:

Consolidate and Externalize CSS:

• Move all inline and duplicated CSS (especially media queries) to an external stylesheet. This will make the code easier to manage and improve caching efficiency.

Optimize JavaScript Event Listeners:

• Consolidate multiple window.addEventListener("load", ...) calls into a single listener to reduce redundancy and improve readability. Combine similar functions, such as updateTheme, updateProgressImg, and updateGitHubIcon, for a more streamlined codebase.

Enhance Accessibility:

• Add aria-labels to interactive elements, especially the theme-toggle button, to ensure screen reader accessibility. Adding role="button" to this element can also improve clarity for assistive technologies.

Remove Duplicate Year Update Script:

• Eliminate one of the duplicate <script> blocks that updates the #current-year element. This will avoid redundant execution and improve code clarity.

Optimize Images with Lazy Loading:

• Add loading="lazy" to all non-essential images, including the GitHub icon, to improve page load performance, especially on slower networks.

These five changes address both performance optimization and code maintainability, resulting in a more robust and user-friendly application.
