Payment Card using some ...long css

hello my friend ♥♥ as first project you start it's good but here some advice for improvement:

• go and search about "centering ways in css" and learn them use them write them some where to become centering master
• use semantics element in you html like <main> , <footer> , <section> , <article> ,etc.
• learn flex box and grid ****** it's very important *****.
• go and see others code you know it's very very good i mean every chllange you complete go and see others solution chllange it's make you learn new things.

and at all for start it was good but make it better and closer to design don't leave it it's bad practice to leave something you know in development . make it better and at last go ahead my friend ♥
