Gamified Quiz Styling and Integration

I'm seeking a developer to enhance and integrate an interactive gamified ethical business quiz for my website, sbcertified.com. I have a functional HTML+JavaScript version, but it requires professional styling and full integration.

Key Requirements:

- Ensure the styling incorporates consistent brand colors.
- Clean up and optimize existing HTML and JavaScript code.

- Integrate the quiz to analyze user's website content via a CORS proxy or backend API.
- Display a pass/fail report with tailored feedback.
- Enable the generation and download of a custom PDF certificate based on the user's score and name.

Ideal Skills and Experience:
- Proficiency in HTML, JavaScript, and CSS, with a focus on Tailwind for styling.
- Experience in code optimization and cleanup.
- Strong understanding of responsive design principles.
- Ability to integrate front-end applications with backend services.
- Familiarity with generating PDF documents programmatically.

Optional:
- Assistance with connecting the quiz to email or backend services in the future.
