Web app - preview rendering

I know there was a post a month or so ago about rendering here, but I was wondering if anyone since has found an optimal way to get things to space correctly in the previewer. I can not figure out the logic - within my web app, a few things will space correctly, but most objects don’t…could it be the previewer itself and the issues would resolve if published? Huge time sink to try and go page by page through trial and error to try and get things to line up…if you have any advice please let me know!

Thanks,
adam
