price component using grid CSS

Hello mates, I have finished this solution. It has really helped me learn Grid CSS and practice it. I have included in the readme file some useful playlist that has helped me a lot (in Arabic). I am trying to know the best practices and how to write both clean code that makes it easy for others to read. I have few question that I'll grateful if you would provide with some answers:

• Do you thing it's OK for me to jump for harder challenges or just take it slowly?
• How do you know if your code is good enough for example if it's good enough for job?
• When is the best time to use flexbox instead of grid?
• Having a portfolio is important, when do you know that you are ready to show off your work? What kind of projects that are worthy to show off?
• Some times I see stuff that can be made using only CSS, but people mostly use JavaScript to do it, is there a reason for it?
• Is it better to do stuff the way you think is good or try to make as it's commonly done?
