I need a thorough recoding and optimization of the CSS for my entire website. It's been two years since the last review and I want to ensure it works seamlessly across all major browsers (Chrome, Firefox, Edge, Safari) and devices (desktop, tablet, mobile). Key Requirements: - Entire website CSS needs updating - No new design elements or features to be added; just optimizing the existing design - No specific issues noticed on certain browsers or devices; a general overhaul is needed - Provide a detailed report on the compatibility and performance of the CSS across all major browsers. - Include before-and-after performance metrics to demonstrate the impact of the optimization. - Update and optimize media queries for better responsive design. - Minify the final CSS files to reduce load times. - Identify and remove any unused CSS to streamline the codebase. - Ensure fallbacks are in place for older browser versions that may not support modern CSS features. - Perform regression testing to ensure that no existing functionality is broken due to the changes. - Ensure that necessary vendor prefixes are included for full browser compatibility. - Make sure the CSS complies with accessibility standards (e.g., WCAG) to support a wider range of users. Ideal Skills and Experience: - Proficiency in CSS and responsive design - Experience with cross-browser and cross-device compatibility - Ability to optimize existing designs without adding new elements - Attention to detail to ensure a flawless user experience across all platforms The CSS update and optimization need to be completed within "as soon as possible." Preferred method of communication during the project is chat. I prefer the CSS optimization to utilize the most common option as the preprocessor. The CSS optimization should utilize "the appropriate preprocessor" as the preprocessor. The preferred CSS preprocessor for this project is Less. Please make use of **any available tools** for troubleshooting and performance analysis.

@webnautical

Hello! As per my understanding your primary goal is to overhaul the current CSS without introducing new design elements. I will focus on refining media queries, ensuring compatibility across all major browsers (Chrome, Firefox, Edge, Safari), and optimizing for various devices. The final CSS will be minified, cleaned of unused styles, and fully responsive, all while ensuring backward compatibility with older browser versions. Additionally, I will provide a detailed report with before-and-after performance metrics. Queries: Are there specific pages or sections that require higher priority during optimization? Do you have existing tools or environments for regression testing, or should I set one up? I am looking forward to working on this project with you! Best Regards, Ravi
