第4列与bootstrap 3.3.7对齐不正确

Question

我正在尝试制作一个包含横幅和4列的网格。该示例可以为seen here。

行之间的间距为10像素，但我无法使框适合，因此它们沿网格中的行移动。当我查看代码时，对我来说看起来是正确的。所以我想这可能是图片的大小。但是改变大小并不能解决我的问题。

有人知道如何使网格元素适合图片中的以下线条吗？

Answer 1

请不要将“ col-”类与“ row”类用于同一元素。

喜欢这个。

<div class="row col-sm-6"> 

因为类名“ row”具有margin-right：-15px;和margin-left：-15px;如果您使用类名“ col-”，它将以padding-right：15px;影响行样式。和padding-left：15px;

这是此问题的主要原因，请再添加一个div结构，例如以下方法

<div class="col-sm-6"> 
     <div class="row"> 

     </div>
</div>

Answer 2

您的代码有很多问题。

其中之一是您使用BS3而不是4。BS3使用float，这是一个不好的做法。请使用BS4与flex。一切都变得容易得多。

另一个是在同一元素上使用2个完全不同的类。 row和col-绝对不能在同一元素上使用。在您的情况下，您需要在列内添加行。

我在您的html中更改了它，并在文件顶部添加了一些CSS。这应该可以帮助您实现所需的目标。

我再次强调您应该使用BS4。

Answer 3

请删除您为col- -和行编写的所有样式。为此使用这种风格

.margin_bottom{margin-bottom:10px;}
.row [class*="col-"]{ padding-left: 5px; padding-right: 5px; }
.row { margin-left: -5px; margin-right: -5px; }

并使用此html代码

<div class="row">
        <div class="col-sm-6 col-md-3 margin_bottom">
            <div class="index-content">
                <div class="card">

Answer 5

您的HTML结构应类似于

const initialObject = [
  {
    'ADF': ['test']
  },
  {
    'BDF': ['test']
  }
  ,
  {
    'CDF': ['test']
  }
];

const finalObject = initialObject.reduce((acc, curr) => {
  const [currentKey] = Object.keys(curr)
  acc[currentKey] = currentKey;
  return acc;
}, {});

console.log(finalObject);
