Twitter Bootstrap Containers

Question

Ive been using bootstrap for a few months and am looking to clarify something as part of best practices.

My question is do I create a container for each row or just

Answer 1

Multiple rows can logically be part of the same grid, like rows in a table. The .container represents one grid. So Example 2 would be the way to go.

Answer 2

I would recommend the second example. In the first you have duplicate code wich makes no real sense. Always think about the principle "Don't repeat yourself".
