在引导网格中添加项之间的边距

Question

我创建了一个具有以下布局的3行的引导网格。

​

​

我所要做的就是在它们之间添加一点空白，但正如您所看到的，列和行不再正确地对齐。

有没有办法解决这个问题，或者有一个更好的方法来实现我想要的？

​

#featured {
  margin-bottom: 15px;
}

.featured-1 {
  height: 200px;
}

.featured-2 {
  height: 50%;
  margin-left: 5px;
}

.featured-3 {
  height: 50%;
  margin-left: 5px;
  margin-top: 5px;
}

Answer 1

已经有填充在列上，它充当排水沟。我会把背景放在你的专栏内容上。

​

#featured {
  margin-bottom: 15px;
}

.featured-1>div {
  height: 200px;
}

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.2.2/dist/css/bootstrap.min.css" integrity="sha384-Zenh87qX5JnK2Jl0vWa8Ck2rdkQ2Bzep5IDxbcnCeuOxjzrPF/et3URy9Bv1WTRi" crossorigin="anonymous">

<div class="container">
  <div class="row" id="featured">
    <div class="col-7 featured-1">
      <div class="bg-warning">Featured 1</div>
    </div>

    <div class="col-5 d-flex flex-column">
      <div class="featured-2 flex-grow-1 bg-danger mb-1">Featured 2</div>

      <div class="featured-3 flex-grow-1 bg-success mt-1">Featured 3</div>
    </div>
  </div>
</div>

<div class="container">
  <div class="row">
    <div class="col-md-12">
      <div class="bg-primary">For reference</div>
    </div>
  </div>
</div>

Answer 2

官方的引导文档推荐使用Gutter。

你可以这样做：

​

.featured-1 {
  height: 200px;
}
.featured-2, .featured-3 {
  height: 50%;
}

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet"
    integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous">

<div class="container">
  <div class="row featured-1" id="featured">
    <div class="col-md-7 col-sm-12 bg-warning">
      Featured 1
    </div>
    <div class="col-md-5 px-4">
      <div class="row featured-2">
        <div class="col-md-12 col-sm-12 bg-danger">
          Featured 2
        </div>
      </div>
      <div class="row featured-3">
        <div class="col-md-12 col-sm-12 bg-success gy-2">
          Featured 3
        </div>
      </div>
    </div>
  </div>
  <div class="row">
    <div class="col-md-12 bg-primary gy-2">For reference</div>
  </div>
</div>
