您是否考虑过通过在单个 .row-fluid 中创建五个 .span 并在每个 span 中再添加两个 .row-fluid 来进行嵌套?这样只有一个***行，标签/字段应该保持在一起.

Have you considered nesting by making a single .row-fluid with five .spans inside it and two more .row-fluids inside each span? This way there is only one top level row, and the labels/fields should stay together.
