I made use of basic HTML and CSS to my knowledge

Try hard brother and see my solution

Maybe this is your first ever project. I can gimme you a tip, try to follow this:

1. color the background
2. color the main box (white box) & set border-radius on it
3. keep add text and background color on other elements
4. try to align main box. In this case, auto margin can work just fine
5. try to structurize the content into section. Hint, there is at least 1 header, 3 sections & 1 sub section. By doing so, you can organize your css and work faster.
6. try to add more padding make it match to the photo (leave the last section for the... very last.)

For the last section (nutrition sect), you can use html table or css grid to make a table. Just play with your imagination.

My code is a bit high level, but you can fire issues to ask me if there is anything you don't know: https://www.frontendmentor.io/solutions/simple-static-site-2h-kuloB9k
