Hey there @gautam_hub, very good job on your project, I saw your project, but you need to change some of the following:
Footer
Change your footer to
position: absolute; bottom:0; left: 0; width:100vw; text-align:center;
so that your footer is below your website and it will be on the center.
Fonts You forgot to change the color for some fonts. you can add classes for each price so you can modify it based on their classes.
Well everything looks good, and good job! Happy Coding! ✌
