Qr-code using html and css

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

I'm proud of developing my first project after learning html and css. I was able to apply concepts like positioning and flexbox. Next time i would like to do a challenge with more components like headers, navigation bar, and footer.

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

I encounter the challenge of responsiveness on mobile device and i used media query to fix it. Also i had challenge in arranging the text space as how they were in the design and i used margin and padding.

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

I would like help in following areas. a)How to view the work how will appear on mobile while developing it so as to achieve responsiveness. I always minimize the browser to see how it will look on mobiles but when i view on mobile i found they are slight different. b)How to determine the values of top and left properties of position when making containers at center. I always guess them while viewing to see if they are at center.
