+# 插槽
+
+  <div style="color: pink;">几何小常识：</div>
+<br>
+
+下方的alert-box是一个组件，和 HTML 元素一样，我们经常需要向一个组件传递内容，像这样：
+
+```javascript
+<alert-box>
+  Something bad happened.
+</alert-box>
+```
+
+可能会渲染出这样的东西：<br>
+![在这里插入图片描述](https://img-blog.csdnimg.cn/7a782ff974ab4eee995d84c15b2a81f1.png)
+
+
+幸好，Vue 自定义的 `<slot>` 元素让这变得非常简单：
+
+```javascript
+Vue.component('alert-box', {
+  template: `
+    <div class="demo-alert-box">
+      <strong>Error!</strong>
+      <slot></slot>
+    </div>
+  `
+})
+```
+
+如你所见，我们只要在需要的地方加入插槽就行了——就这么简单！

+
+
+下列关于插槽描述错误的是？<br/><br/>
+
+## 答案
+
+Vue中使用插槽是为了解决解决组件美观问题。
+
+## 选项
+
+### A
+
+插槽就是子组件中的提供给父组件使用的一个占位符
+
+### B
+
+父组件可以在插槽中添加 HTML、组件等填充信息。
+
+### C
+
+具名插槽通俗的讲其实就是给插槽取个名字。
