The display on the mobile is bad

I use helix3 framework and on the mobile the display is very bad as in other sites that use os property.

i want add css classes in div: span4, content span8, span 12 and all div of Property listing layout and detail property.
i want modify the structure of layout ( div item-photo outside of div span4 ) but I did not find any guide.

Hi Dam,

Is there a fix for this as I have 2 OSproperty sites and both look awful on mobile... I am sure they didnt look like this before. Both site have different versions of OS Property installed

many thanks
Alan

Hi Alan,
OS Property has responsive layouts, but they are also depend on your current using template. If your template doesn't work well on mobile, the layouts of OS Property won't show well on mobile too.
You can submit ticket on category OS Property to provide your site url with super admin account. I'll check your template and OS Property system before we can provide suggestion to solve the stylesheet layouts
Thanks
