No space at the beginning
Problem
The space that appears on the 3rd line is a “feature” of bootstrap : the first span of a container has no left margin.
(source : https://github.com/twitter/bootstrap/blob/master/less/mixins.less#L613)
Fix
You can add an invisible .span element before the first item : that way the first item will have a space too.
Hole in the layout
Problem
Your first item seems to be longer (in height).
Fix
It appears you have set a minimum height, but you should fix a maximum height, or ensure that there are no items longer than the minimum height.
