                <p>建立在我们的 flexbox 实用程序之上的速记助手，使组件布局比以往更快、更容易。</p>
                <p>Stacks 提供了一种快捷方式，可以应用许多 flexbox 属性在 Bootstrap 中快速轻松地创建布局。 这个概念和实施的所有功劳都归功于开源 <a href="https://almonk.github.io/pylon/" target="_blank">Pylon 项目</a>。</p>
                <div class="callout callout=warning mb-3">当心！ Safari 最近添加了对带有 flexbox 的间隙实用程序的支持，因此请考虑验证您的预期浏览器支持。 网格布局应该没有问题。 <a href="https://caniuse.com/flexbox-gap" target="_blank">阅读更多</a>。</div>

                <h6>垂直的</h6>
                <p>使用 <code>.vstack</code> 创建垂直布局。 默认情况下，堆叠的项目是全宽的。 使用 <code>.gap-*</code> 实用程序在项目之间添加空间。</p>
                <div class="border-example">
                  <div class="vstack gap-3">
                    <div class="bg-light border">第一项</div>
                    <div class="bg-light border">第二项</div>
                    <div class="bg-light border">第三项</div>
                  </div>
                </div>
                <pre>&lt;div class="vstack gap-3"&gt;
        &lt;div class="bg-light border"&gt;第一项&lt;/div&gt;
        &lt;div class="bg-light border"&gt;第二项&lt;/div&gt;
        &lt;div class="bg-light border"&gt;第三项&lt;/div&gt;
      &lt;/div&gt;</pre>

                <h6>水平的</h6>
                <p>使用 <code>.hstack</code> 进行水平布局。 默认情况下，堆叠的项目垂直居中，并且只占用它们必要的宽度。 使用 <code>.gap-*</code> 实用程序在项目之间添加空间。</p>
                <div class="border-example">
                  <div class="hstack gap-3">
                    <div class="bg-light border">第一项</div>
                    <div class="bg-light border">第二项</div>
                    <div class="bg-light border">第三项</div>
                  </div>
                </div>
                <pre>&lt;div class="hstack gap-3"&gt;
        &lt;div class="bg-light border"&gt;第一项&lt;/div&gt;
        &lt;div class="bg-light border"&gt;第二项&lt;/div&gt;
        &lt;div class="bg-light border"&gt;第三项&lt;/div&gt;
      &lt;/div&gt;</pre>

                <p>使用 <code>.ms-auto</code> 等水平边距实用程序作为分隔符：</p>
                <div class="border-example">
                  <div class="hstack gap-3">
                    <div class="bg-light border">第一项</div>
                    <div class="bg-light border ms-auto">第二项</div>
                    <div class="bg-light border">第三项</div>
                  </div>
                </div>
                <pre>&lt;div class="hstack gap-3"&gt;
        &lt;div class="bg-light border"&gt;第一项&lt;/div&gt;
        &lt;div class="bg-light border ms-auto"&gt;第二项&lt;/div&gt;
        &lt;div class="bg-light border"&gt;第三项&lt;/div&gt;
      &lt;/div&gt;</pre>

                <p>并使用垂直规则：</p>
                <div class="border-example">
                  <div class="hstack gap-3">
                    <div class="bg-light border">第一项</div>
