I just publish my new web pages but also I found issues.
If you check the pages via computer this looks good but if i use mobile phones web pages is not good. The vertical position of the pages is ok but the horizontal version is mixed somehow. What is easy way copy basic page to mobile version?
The mobile version is a css controlled version of main version - on detection of a mobile device screen the styles for layout, menus etc are switched to the mobile friendly version.
The website variants dimensions are set in the dialog shown below - depending on the starting template yours may have different values
You could try adjusting these to see if you can improve the horizontal - I would suggest you create a copy of the original project as a backup. See the section Responsive web design in Help or the PDF manual if you have it.
