I hope that this is not a silly question - Joomla! Forum - community, help and support

hi
i hope not silly question, have had enough of these me in past.

i looking create website 3 templates, 3 column (desktop), 2 column (tablet) , single column (mobile). looking way maintain single source of content, articles.

i have mentioned in other posting use artisteer, within can produce fluid type templates.

i have means of user switched appropriate template.

my problem how can use single source of content @ same time populate individual templates, can point me right direction, possible.

if website detects user statioinary/laptop computer or tablet user or mobile phone, can direct user use right template, can't it?
then need publish 1 place, display accoriding , visitor using.

that @ least how works on many new templates can buy.
just make sure template can handle user device detection, , rest should automatic.
at least how have understood it.
