Bootstrap 3-网格系统和缩略图

Question

My grid system is like that:

I want to put it side by side. I'm trying to do that:

My code actually is:

 <div class='row'>
  <div class='col-sm-6 col-md-4'>...</div>
  <div class="col-sm-6 col-md-4">...</div>
  <div class="col-sm-6 col-md-4">...</div>
  <div class="col-sm-6 col-md-4">...</div>
 </div>

How can I do that? I'm looking in the internet (google, forum, ...), but it's hard to find. I'm trying to use only bootstrap. I don't want plugins or something like that.

Answer 1

In your scenario you should keep only 3 columns for grid and move 4th column content to first column.

<div class='row'>
  <div class="col-sm-6 col-md-4">... [add 4th column content here]</div>
  <div class="col-sm-6 col-md-4">...</div>
  <div class="col-sm-6 col-md-4">...</div>
</div>

But it also depends what you want to have on smaller resolutions.
