为什么网站的右下角有多余的空间？

Question

我正在尝试删除网站底部和右侧的空白区域。在右侧，它似乎是由黑色导航栏引起的，但我不知道如何修复它。

Answer 1

我认为这是您的顶级嵌套。您还需要将 jumbotron 包装到容器 div 中。如果你需要全宽，你可以让它变得流畅：

<div class="container-fluid">
    <div class="row">
    ...
</div>

一般来说，如果您查看基本的templates provided by boostrap's documentation，它们会将所有正文内容放入容器 div 中。

这是因为每一行都有一个-15px 边距。

Answer 2

这是由您的引导程序引起的： 每个.row 的左右边距为负，而每个.col-* 的左右边距相同。

我们必须摆脱它。但是我们需要它回到 .container 类中。

看这里：https://codepen.io/anon/pen/QpOyyo

我添加了这个 CSS：

/* Don't add padding to all elements that have classes like "col-md-*" */
[class^="col-md-"], 
[class*=" col-md-"] {
  padding-right: 0;
  padding-left: 0;
}
/* Add back the Bootstrap padding, if inside .container */
.container [class^="col-md-"], 
.container [class*=" col-md-"] {
  padding-right: 15px;
  padding-left: 15px;
}

/* Don't add negative margin for all rows */
.row {
  margin-left: 0;
  margin-right: 0;
}

/* Add back the Bootstrap margin, if inside .container */
.container .row {
  margin-left: -15px;
  margin-right: -15px;
}

更新：也添加此内容以解决页脚问题。

.container-fluid {
  padding-right:0px;
  padding-left:0px;
}

footer p{
  margin:0;
}

Answer 3

它是由 div .col-md-12 上的 padding-right 引起的。将其设置为 0 就可以了。 底部的空白是由页脚中的#copy引起的，添加margin-bottom：0。
