Hello,
Please read my proposal before deciding
I have one question before (if u consider) picking my bid.
Did you tested any of your non-responsive sites on actual mobile device?
Seems to me like in your case it is not problem with script that is testing your site, rather the way you see your non-responsive site on mobile testing sites (partial view), is actual thing you would see on real mobile device.
I am pretty sure that is the case. Some browsers on mobile devices will scale down site automatically for you, but (this is important) this is browser doing it not the site itself, you could say that browser is fixing your site automatically. And the best way to change that is to just fix your site's code and then i'm sure your fixed width site will show itself full on any online responsive website check sites.
I hope you read my solution to your problem.
And i will explain the code you need to add alongside your "fixed width" site code so it will work fine on any size device (and responsive website check) .
I will do that for you for $5 ( + $5 commission that goes to this website) and a nice review.
You can contact me if you have any questions via pm, e-mail or skype, my skype id is: "live:kristijan.sekeres_1"
Also if you still want your own script for checking site responsiveness i can make that too, in that case we will further discuss payment.
Kind Regards,
Kristijan S.
