Using bootstrap

Deep, In this Project I think you need to take a look at Design because those Boxes are white and Yours Boxes are looking Grey Please take a look at Design And On Clicking Select Reward button. There is no Modal popping up take a look at that There is course in Frontend Mentor site for Responsive ness and It's Completely free in Resource section. My personal Suggestion would be Start from Newbie Projects If you are completely New to Frontend & then Progress According to your skillset and also watch YouTube videos of Online Tutorials Channel you might also get better idea of Frontend and other channels also. Good Luck & Happy Coding.
