Chall SCSS, Grid, Flex and Responsive

Hello guys ! I just finished this challenge, and it was very cool ! I had some difficults like the <section1>' background, the image is not enought curved (I had to put "center/cover" because with a same color in background to fill the holes, there was no more "wave", like here in responsive) and for the link "See how Fylo works" if I didn't put the image in the paragraph, the border was broken in the good alignment. I really appreciate coding !
