For the past week I have been working on restyling tabs on a widget. Some problems I have encountered during the restyle is our 960 grid system which with a side navigation included allows me a space of 12 cols to work with.
While researching, top tab placement seemed to be a common pattern used. However if more tabs are added to max out the first row a second row is created which isn't very eye-catching.
Side tab placement would allow the widget to display tabs in a single row going downwards. However less content doesn't look good in a large container.
What is the best practice for tab placement on a widget? Which would provide for a better user experience?
