你可以使用colx -xs-*类来实现列与列之间的间隔，在下面编码的colx -xs-* div中。间距是一致的，这样所有的列都能正确对齐。为了获得均匀的间距和列大小，我将执行以下操作:

<div class="container">
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
    <div class="col-md-3 ">
        <div class="col-md-12 well">
            Some Second Content..
        </div>
    </div>
</div>

这将是有用的。

.list-item { margin-right: -10 px; margin-top: 10 px; margin-bottom: 10 px; 边框:1px实体#eee; 填充:0 px; ｝ < div class = " col-md-4”> < div class = "列表项”> 你的名字< h2 > < / h2 > < / div > < / div > < div class = " col-md-4”> < div class = "列表项" > < / div > < / div >

如果想要增加或减少框的右边的边距，只需编辑列表项的右边距属性。

样例输出

很简单。你必须添加固体边界右，左col-* 它应该是工作…:)

它看起来像这样:http://i.stack.imgur.com/CF5ZV.png

HTML:

<div class="row">
     <div class="col-sm-3" id="services_block">

     </div>
     <div class="col-sm-3" id="services_block">

     </div>
     <div class="col-sm-3" id="services_block">

     </div>
     <div class="col-sm-3" id="services_block">

     </div>
</div>

CSS:

div#services_block {
   height: 355px;
   background-color: #33363a;
   border-left:3px solid white;
   border-right:3px solid white;
}

引导4，文件自定义。SCSS您可以添加以下代码:

$grid-gutter-width-base: 20px;

$grid-gutter-widths: ( xs: $grid-gutter-width-base, 
sm: $grid-gutter-width-base, 
md: $grid-gutter-width-base, 
lg: $grid-gutter-width-base, 
xl: $grid-gutter-width-base
);

默认$grid-gutter-width-base: 30px;

在冷-md-?，创建另一个div，把图片放在那个div，然后你可以很容易地添加填充像这样。

<div class="row">
  <div class="col-md-8">
     <div class="thumbnail">
       <img src="#"/>
     </div>
  </div>
  <div class="col-md-4">
     <div class="thumbnail">
       <img src="#"/>
     </div>
  </div>   
</div>

<style>
  thumbnail{
     padding:4px;
           }
</style>

我不认为你能做到这与Bootstrap单独。列与列之间的空间会自动添加/维护。 如果你需要在列之间添加一个特定的宽度，你可以做这个技巧来模拟空间:https://jsfiddle.net/loginet/3rogbh9s/5/

<div class="row">
    <div class="col-6">
        <div class="left-column">Left column</div>
    </div>
    <div class="col-6">
        <div class="right-column">Right column</div>
    </div>
</div>

和CSS

.left-column {
    padding: 10px;
    padding-right: 50px;
    background: white;
}

.right-column { 
    padding: 10px;
    padding-left: 50px; 
    background: white;  
}
