基本结构，具备响应式布局功能，主要断点为 768px 和 576px，拖动窗口改变大小试试看。

```ts
import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  selector: 'app-demo',
  template: `
    <page-header
      [title]="'title'"
      [breadcrumb]="breadcrumb"
      [logo]="logo"
      [action]="action"
      [extra]="extra"
      [content]="content"
      [tab]="tab"
    >
      <ng-template #breadcrumb>面包屑</ng-template>
      <ng-template #logo><div class="logo">logo</div></ng-template>
      <ng-template #action><div class="action">action</div></ng-template>
