Hi @tuanphan ! Thank you very much for your help ! I tried the code block, the design is working but a big black stain still appear in the middle and the parallax also mess up the whole page. I think it is rather complicated to export such heavy design and the parallax effect doesn't make things easier, so no worries.
Actually I would like to use this other codepen instead https://codepen.io/isladjan/pen/bGpjZwN
if you can also help me with this one ? Ideally I would like to export it without the button Go Fullscreen, also for squarespace 7.1, thank you very much in advance !
Best regards
