导航栏
</h1>
<p class="bd-lead">Bootstrap强大的响应式导航标题，导航栏的文档和示例。包括对品牌，导航等的支持，包括对我们的折叠插件的支持。</p>
<h2 id="这个怎么运作">这个怎么运作</h2>
<p>在开始使用导航栏之前，您需要了解以下内容:</p>
<ul>
<li>Navbars需要使用<code class="highlighter-rouge">.navbar-expand {-sm | -md | -lg | -xl}</code>包装<code class="highlighter-rouge">.navbar</code>以进行响应式折叠和[颜色方案]（＃颜色方案）类。</li>
<li>默认情况下，Navbars及其内容是流畅的。 使用[可选容器]（＃containers）限制其水平宽度。</li>
<li>使用我们的[spacing]（{{site.baseurl}} / docs / {{site.docs_version}} / utilities / spacing /）和[flex]（{{site.baseurl}} / docs / {{site.docs_version} / utilities / flex /）用于控制导航栏中间距和对齐的实用程序类。</li>
<li>默认情况下，导航栏会响应，但您可以轻松修改它们以更改它。 响应行为取决于我们的Collapse JavaScript插件。</li>
<li>打印时默认隐藏导航栏。 通过将<code class="highlighter-rouge">.d-print</code>添加到<code class="highlighter-rouge">.navbar</code>来强制打印它们。 请参阅[display]（{{site.baseurl}} / docs / {{site.docs_version}} / utilities / display /）实用程序类。</li>
<li>通过使用<code class="highlighter-rouge">&lt;nav&gt;</code>元素确保可访问性，或者，如果使用更通用的元素（如<code class="highlighter-rouge">&lt;div&gt;</code>），则为每个导航栏添加一个`role =“navigation”以明确地将其标识为用户的标志性区域 辅助技术。</li>
</ul>
<p>继续阅读示例和支持的子组件列表。</p>
<h3 id="导航">导航</h3>
<p>Navbar导航链接使用自己的修饰符类构建我们的<code class="highlighter-rouge">.nav</code>选项，并且需要使用[toggler classes]（#toggler）来实现正确的响应式样式。导航栏中的导航也将增长到占用尽可能多的水平空间，以保持导航栏内容安全对齐。</p>
<p>活动状态 - 使用<code class="highlighter-rouge">.active</code>-表示当前页面可以直接应用于<code class="highlighter-rouge">.nav-link</code>s或它们的直接父.<code class="highlighter-rouge">nav-item</code>s。</p>

<p>由于主题类和<code class="highlighter-rouge">background-color</code>实用程序的组合，主题导航栏从未如此简单。选择<code class="highlighter-rouge">.navbar-light</code>用于浅色背景颜色，或<code class="highlighter-rouge">.navbar-dark</code>用于深色背景颜色。然后，用`.bg-自定义</p>

<p>使用我们的[位置实用程序]（{{site.baseurl}} docs {{site.docs_version}}实用程序位置）将导航栏放置在非静态位置。选择固定到顶部，固定到底部，或粘贴到顶部（滚动页面，直到它到达顶部，然后停留在那里）。固定的导航栏使用<code class="highlighter-rouge">position：fixed</code>，这意味着它们是从DOM的正常流程中拉出来的，并且可能需要自定义CSS（例如，<code class="highlighter-rouge">&lt;body&gt;</code>上的<code class="highlighter-rouge">padding-top</code>）以防止与其他元素重叠。</p>
<p>还要注意<code class="highlighter-rouge">.sticky-top</code>使用<code class="highlighter-rouge">position：sticky</code>，[在每个浏览器中都不完全支持]（https://caniuse.com/#feat=css-sticky）</p>
