I have three questions about this challenge:

1 - How to properly implement the background-image(the wave svg one)? I've tried many things, but all would ended up not matching the real design.

2 - In the Testimonials Section, the Quote Icon is not working with z-index: -1. What can I do?

3 - I've used <br> on the headings like "All your files in one secure location, <br> accessible anywhere." Is there a better way to make line breaks without <br>?

I really appreciate the attention.

Any suggestions would be greatly appreciated!

Any tips would be nice :)

It was really fun building this card. This is my first project without tutorial hell.
