👋Hi Vishal!

I have some suggestions for this solution:

• You can try to use rem units and start get familiar with it by doing Frontend Mentor challanges. Basically 1rem is equal to 16px (if you don't change the font size on your browser setting).
• I recommend for * (universal selector) or as a reset, try to add box-sizing: border-box to prevent all elements to do something funny, like adding additional width when adding border or padding
• You can try to use BEM methodology for giving class name. It will make you write a better CSS!
• You can try to learn CSS custom properties to prevent you from keep repeating the color code.

That's it! Hopefully this is helpful!

Nice work.
