Worked on the iiuni/projektzapisy repository to refactor the course header user interface, focusing on improving readability, accessibility, and maintainability. Applied semantic HTML using unordered lists to structure hours, tags, and learning outcomes, and enhanced the visual presentation with targeted CSS updates. Addressed DOM-related issues in the course item template to reduce fragility and improve screen reader support, resulting in a more consistent and accessible experience for both students and instructors. Leveraged skills in CSS, Django templating, and HTML to deliver changes that streamline future development and onboarding, while ensuring the course summary details remain clear and easy to maintain.
