I have been playing with various themes like the html5 initializer,Jedi and html5 responsive themes. I currently have my
own customized theme created but what would really put the icing on the cake would be a browser width responsive theme
like the current liferay.com site...where can i i find this...i downloaded the latest liferay 6.1 beta community edition but it does not
contain this theme..where can i find it?..

Failing this where can i find the actual mobile/tablet theme with the vertical menu style for viewing on smartphones and tablets

Here you have the instructions of how they did it:

Thanks for this..very interesting article..I take it this means I will have to implement this theme myself...Am using the jedi mobile theme from liferay 6.0.1..with some customization i think it will suit my needs enough for now...
