Inconsistent between live site and preview

I have calculated very carefully all the measurements. That’s why it’s so frustrating that the live site when I published, a lot of measurements go wrong compared to the preview. Please guide me how to fix this, I spend a lot of time on these measurements.

I also got this problem between preview of tablet and live site

I saw you opened a ticket with support but it could be the margin for the textbox might be a fixed margin so the spacing looks okay on one breakpoint but is not enough on larger breakpoints.

For the text box issue, if it’s one textbox, would recommend to check that the width isn’t perhaps set to 0px/0% and it’s causing all the text to collapse. Alternatively, might recommend see if it happens with another textbox.
