We just finish http://acimcentre.org/ and are testing responsive layout. We found several problems:
Using different devices the "right margin" is NOT working properly on the following devices.
1 )iPad 2 OS 6.1 [10b141] Browser Safari (latest version)
2) iPhone 5 (latest version)
3) Samsun Droid Charge SCH-I510 (latest version software)
See screen shot on Samsun: http://acimcentre.org/wp-content/uploads/2013/02/Screen-shoot-Samsun-Droid-Charge.jpg
The other devices would have had same screenshot problem. Note the cut on text on right margin.
Your tech support is appreciated. Thank you.
