I need to give styles to the mobile layout for omega theme in drupal 7.
I have found the options under appearance -> layout configuration -> Grid settings for Normal, Narrow,Wide and Fluid. Hence i got the stylesheets for my theme under sites->all->themes->mytheme-> as default.css,narrow.css,wide.css,normal.css. But how can I write for 320px media queries?
How can i create a style sheet for mobile layout? Can any one help me Please.
