Webpage doesn’t look like Elementor edit

Hello,

I work with Elementor and OceanWP( theme ) on my website.

In the Elementor editor (mobile, tablet, desktop ), everything looks great but when I look at the webpage in the browser the layout ( mobile, tablet, desktop ) is not identical at all.

I hope someone can help me to locate the problem

Thank you!

Best, Parisa
