You can display content inside columns in Ozcart that safely scale down to smaller devices (responsive web design), by taking advantage of the Shortcodes feature built-in to Ozcart.
Columns need to be wrapped in starting and ending tags that relate to the proportion that you wish them to take on.
You have the following choices
This is the default - you don't need any shortcodes to display content using the full width available in the middle panel of the screen. Just enter your content without wrapping it in any short codes.
Wrap each column of content in [one_half][/one_half] tags
Wrap each of your column's content in [one_third][/one_third] tags
Wrap each of your column's content in [one_quarter][/one_quarter] tags.
Important note: Make sure that you do NOT put line breaks/new lines between sections - so the three one_third tags must be wrapped together on a single line to be displayed correctly.
