Why is the adaptive clumsily displayed?

Question

css

Good evening! Tell me why the site is clumsily displayed? I started adapting to it via media . Most emails are not displayed at 100% screen width. But mostly by 50-60%. I browse through safari, iPhone 5s.
So far, only the adaptive menu has been made. After I started to adapt the content and ran into this problem. Tell me what to do)

Answer 1

if only because you
have .block1 {
width: 415px;
height: 585px;
}
if you are responsive, what are the pixels in width?
