Why designer and published site are different?

Hi all,

I desperatly try to make my first website in webflow and I really start to loose any hope of having something correct…

I use chrome on a 1920x1080 px laptop. So I set up my designer canvas to 1920px 100% zoom, make my design and when I publised the site, it’s not working…

How can I set my canvas to have the site exactly as it is in the designer?

here’s my read only

thx all!
