Fetze, I have looked but I cannot see any issues. Is the problem only on mobiles only? Perhaps a couple of screen shots to identify the problem would assist??

Fetz, I assume you do not like the gaps as in the second screen shot.

I can see that the 1st site has a header and is possibly generated from a template, whereas the second site does not appear to have a header (each page has a different menu) and I am guessing you created the pages with a blank template.

The display width on the mobile will be affected by page width, margins, object margins, etc. and these would need to be identical to the layout of the 1st site if you want them to display the same.

If it was me, I would copy the 1st site and work on 2 different projects that are both based on the same template structure so they display the same (& not use the blank template page option). In the copy simply modify the header to be suitable for site 2, modify the home page and remove unnecessary pages. You would then upload 2 separate projects each to their own domain name without having to resort to a manual page with frames for the 2nd site.

In the pro version (I am not sure if it exists in evo) there is also the option to extend an object to use the whole width of the browser, this quite nicely does away with the need to think about page sizes and break points and will always fill the width of a mobile (or desktop). Unfortunately this limits you to one object/cell per line.

I hope I have guessed correctly.
