I am testing Twitter Bootstrap and got stuck with basic scaffolding with rows. I revisited their documentation number of times and I can see nesting columns where you can basically nest columns within a column but I cannot locate the capability of combining rows into one and have it aligned with column next to the uncombined rows.
Below picture should illustrate what I want to accomplish.
The only workaround solution I came across is using tables but I don't like this idea as my view is that the responsiveness wouldn't work with the use of tables.
Does anyone have any elegant solution to this? Most of the web layout I do will need fine level of flexibility so it will be great if I could pick up something useful here.
