Playing with a purchased theme and in the documentation I see this in the short codes section:
... - the given shortcodes are used for the layout framework on the basis of 960gs.
... - the given shortcodes are used for the layout framework on the basis of fluid columns
Can someone explain what grid columns and fluid columns are and what this documentation could possibly mean? Of course you don't have the theme and you'll be guessing but I'll appreciate your insight.
