html - 如何使用 css 制作一个像 bootstrap 弹出窗口一样的 div

Question

我有一个表，其数据来自循环，这里有一个“单击此处”链接，当您单击链接时，div 将以绝对位置打开，我想将此 div 制作为带有 css 的引导模式。如果可以使用 Bootstrap 就可以了。当您按下关闭按钮弹出窗口应该像 Bootstrap 一样关闭。这是下面的代码

app.component.html

<table class="table border">
    <thead>
    <tr>
      <ng-container *ngFor="let column of columns; let i = index">
        <th>{{ column }}</th>
      </ng-container>
    </tr>
    </thead>
    <tbody>
        <tr *ngFor="let row of groups;let i = index">
            <td>{{row.name}}</td>
            <td>{{row.items}}</td>
            <td>{{row.Status.length}}-<span (click)="hideme[i] = true" style="border:1px solid;" >Click here</span>
               <div style="position:absolute;top:10px;border:1px solid;padding:20px;position:absolute;background:#fff;" [hidden]="!hideme[i]"> <span  *ngFor="let item of row.Status;let j = index">
                    {{item.name}}
                    <span *ngIf="j != row.Status.length - 1">,</span></span><span (click)="hideme[i] = false" style="position: absolute;
    top: 0;
    right: 0;cursor:pointer;">close</span></div>
           </td>
            <td>
                <span *ngFor="let item of row.loc;let k = index">
                   {{item.name}}
                   <span *ngIf="k != row.loc.length - 1">,</span>
                </span>     
           </td>
        </tr>
  </tbody>
  </table>

可以在以下位置测试代码:stackblitz

从 W3Schools 获得了一些代码，还添加了 2 个接受索引的 javascript 函数。代码是不言自明的。

app.component.html

<table class="table border">
    <thead>
    <tr>
      <ng-container *ngFor="let column of columns; let i = index">
        <th>{{ column }}</th>
      </ng-container>
    </tr>
    </thead>
    <tbody>
        <tr *ngFor="let row of groups;let i = index">
            <td>{{row.name}}</td>
            <td>{{row.items}}</td>
            <td>{{row.Status.length}}-<span (click)="displayBox(i)" style="border:1px solid;" >Click here</span>
               <div  class="modal" id="model_{{i}}" style="display:none;">
                  <div class="modal-content">
