Twitter Bootstrap 不显示装订线

Question

我正在使用 twitter bootstrap 3 创建一个网站模板，据我所知，它通常在大型显示器的两侧都有一个 15 像素的装订线，我没有得到 div 之间的装订线。

    <!DOCTYPE html>
<html lang="en">

    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <!-- Bootstrap -->
    <link href="bootstrap/css/bootstrap.min.css" rel="stylesheet">

    <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->

<h1>Hello, world!</h1>
<div class="container">
    <div class="row">
<div class="col-lg-3" style="background-color:red; height: 80px;">test</div>
<div class="col-lg-3" style="background-color:red; height: 80px;">test</div>
<div class="col-lg-3" style="background-color:red; height: 80px;">test</div>
<div class="col-lg-3" style="background-color:red; height: 80px;">test</div>
    </div>
</div>

Answer 1

Boostrap 行有 15px 左右负边距 margins，列分别有 15px 左右 padding。因此，您不会在列中看到 'gutter'。然而，如果你想创建一个类似装订线的效果，你可以这样做：假设你想要在每列之间有一个 2px 的装订线。除了所需的 15 像素外，还向列填充添加 1 像素。

CSS:

div.col-lg-3 {
  padding-left: 16px; // gutter / 2
  padding-right: 16px; // gutter / 2
}

不要在列中添加边距。

Answer 2

尝试将方框放在列内。

<div class="container">
    <div class="row">
        <div class="col-lg-3">
            <div style="background-color:red; height: 80px;">test</div>
        </div>
        <div class="col-lg-3">
            <div style="background-color:red; height: 80px;">test</div>
        </div>
        <div class="col-lg-3">
            <div style="background-color:red; height: 80px;">test</div>
        </div>
        <div class="col-lg-3">
            <div style="background-color:red; height: 80px;">test</div>
        </div>
    </div>
</div>
