Hi,
http://jsfiddle.net/efp8z6Ln/363/
In the first gird, you can see that there is space between the two columns.
But in the second grid when we put the columns inside a .row the space is gone.
I may be wrong but the rows of the columns in the first example are implicit. Each column must look as if it had a .row parent. Your first example has two rows and your second example has only one row.
See: http://jsfiddle.net/b6v9y335/
@shadoWalker89: As per the docs: Rows are groups of columns which are aligned horizontally.
Hence, two columns which are vertically aligned don't have the same spacing if they aren't in a row.
you can do something like this: http://jsfiddle.net/vinayakkulkarni/dt7zwkhm/ or what @meze suggested.
If you have any suggestions, queries or problems, just ping in Gitter or post a thread on SUI Forums
Closing this now 馃槈
Thanks guys
