The support.ini file located in a theme directory ('root/themes/your_theme') shows the lowest version of a device and a browser that is supported by the system.
The entries in the support.ini file have the following format:
You can use an exception theme when the website is opened with an earlier version of a browser/device. For example, if you remove the comment character (;) in front of "firefox=5", when the website is opened with Mozilla Firefox version earlier than 5, it will use an exception theme.
;android=0 firefox=5 ;msie=7 ;opera=11 ;chrome=14 ;safari=6
Adding an Exception Theme
You can download the example exception theme and put its content in the 'root/themes/your_theme/exception' directory.
Using a Mobile Exception Theme
If you remove the comment character in front of "android=0", when the website is opened with any Android version it will use the mobile theme located in the 'root/themes/your_theme/exception/mobile' directory.
