It took a little longer than i expected, i found difficult on making the validation and i'm not sure i made it in the best way, since i used an input type="text" on email to avoid the default message. Feedbacks are welcome.
Your code is very good, well done!
Just a small thing that can help you, but it's not really necessary : Instead of setting margin : 0 or padding : 0 for each element, you can maybe use CSS Reset
Personally, I use :
*{
padding : 0
margin : 0
box-size : border-box
}
But choose what seems to be good for you, as I said it can even be skipped. Once again, your code is very good ! Have a nice day !
I think you can improve the responsive layout by using the <picture> and <source> elements to change the image source in relation to the viewport width.
Here is a link if you need more information: HTML <picture> element.
Above all, your code is great, well done!
