Issues with appearance in Edit Page mode

Hello,

I am making a website on wordpress and have been really struggling with this issue. I can’t seem to find out where I’ve gone wrong.

When I look at my pages in editing mode they look completely different than they do once published. Ideally I would be editing the same thing that actually shows up on my page.

If anyone can help it would be very much appreciated!
