I just have one simple question, is there a way I can set the page size to fill all types of screen size automatically? We have a template which works well on laptop and mobile but we had added more pages and the pages do not seem to fit the entire screen on the laptop and its too big on the mobile.
Yes, you need to make you page responsive. You can check the responsive tab in the editor and adjust your setting there. It’s not easy at first, but once you get the hang of it and understand the concept, it’s not that hard.
