为了获得列之间特定宽度的间距，我们必须在标准Bootstrap的布局中设置填充。

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css'); /* Check breakpoint at http://getbootstrap.com/css/#grid-media-queries */ @media (min-width: 992px) { .space-100-px > .row > .col-md-6:first-child { padding: 0 50px 0 0; /* The first half of 100px */ } .space-100-px > .row > .col-md-6:last-child { padding: 0 0 0 50px; /* The second half of 100px */ } } /* The result will be easier to see. */ .space-100-px img { width: 100%; height: auto; } <div class="container-fluid space-100-px"> <div class="row"> <div class="col-md-6"> <img src="http://placehold.it/450x100?text=Left" alt="Left"> </div> <div class="col-md-6"> <img src="http://placehold.it/450x100?text=Right" alt="Right"> </div> </div> </div>

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;

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>

用css添加一个与背景颜色相同的边框怎么样?我是新手，所以也许有一个很好的理由不这样做，但当我尝试它时，它看起来很好。

在最新的引导版本中，您可以使用“卡片”

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;  
}
