使用Bootstrap3和网格系统.网格系统中的默认设置为12列.

写html是否有任何不良后果类似于:

<div class="row">
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
    <div class="col-md-12">...</div>
</div>

要么

<div class="row">
    <div class="col-md-4">...</div>
    <div class="col-md-4 hidden">...</div>
    <div class="col-md-4">...</div>
    <div class="col-md-4 hidden">...</div>
    <div class="col-md-4">...</div>
    <div class="col-md-4 hidden">...</div>
    <div class="col-md-4">...</div>
    <div class="col-md-4 hidden">...</div>
</div>
