Responsive QR Code Component Using Flexbox

What are you most proud of, and what would you do differently next time?

I’m most proud of how precise I was with spacing and alignment. Even though this challenge looks simple, getting the layout to match the design exactly required attention to detail especially with padding, font sizing, border-radius layering, and centering the card both vertically and horizontally.

I’m also proud of keeping the HTML structure clean and semantic instead of overcomplicating it with unnecessary wrappers.

Next time, I would approach it with a stronger mobile-first mindset from the very beginning. While the layout is simple, I want to improve how I think about scalability and structure my CSS in a way that’s more reusable for larger projects.

What challenges did you encounter, and how did you overcome them?

The main challenge was achieving perfect vertical and horizontal centering without breaking responsiveness. Initially, I experimented with margin-based centering, but it wasn’t as clean or scalable.

I resolved this by using Flexbox on the body element, which provided a more reliable and modern solution. Another small challenge was fine-tuning the typography to closely match the design. Adjusting font weights, sizes, and line heights helped achieve a closer visual match.

Overall, this project reinforced how important spacing discipline and layout fundamentals are in frontend development.

What specific areas of your project would you like help with?

I would appreciate feedback on my layout structure and CSS organization. Although the design is simple, I want to ensure I’m following best practices when structuring my styles for scalability and maintainability.

I’d also like input on whether my spacing values (padding, margin, line-height) are well-balanced and aligned with the design system. Small spacing inconsistencies can affect the overall visual polish, and I’m working on improving that level of detail.

Additionally, I’d welcome suggestions on accessibility improvements, particularly around semantic HTML usage and how I could make this component more robust in a real-world production environment.
