在旋转器Angular后面的模糊背景

我在加载任何数据时在Angular代码中使用微调器。我为它创建了一个单独的组件(下面给出了必要的文件)。我的微调器看起来像这样:

现在,我需要在旋转器后面显示加载图标的同时模糊微调器后面的背景。知道怎么做到了吗?

spinner.component.ts:

import { Component } from "@angular/core";

@Component({
    selector: "loading-spinner",
    templateUrl: "./spinner.component.html",
    styleUrls: ["./spinner.component.css"]
})
export class SpinnerComponent{

}

spinner.component.html:

<div class="spinner">
    <div class="rect1"></div>
    <div class="rect2"></div>
    <div class="rect3"></div>
    <div class="rect4"></div>
    <div class="rect5"></div>
  </div>

spinner.component.css:

.spinner {   
    width: 50px;
    height: 40px;
    text-align: center;
    font-size: 10px;
    position: fixed;
    z-index: 1500;
    overflow: show;
    margin: auto;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
  }

  .spinner > div {
    background-color: #333;
    height: 100%;
    width: 6px;
    display: inline-block;

    -webkit-animation: sk-stretchdelay 1.2s infinite ease-in-out;
    animation: sk-stretchdelay 1.2s infinite ease-in-out;
  }

  .spinner .rect2 {
    -webkit-animation-delay: -1.1s;
    animation-delay: -1.1s;
  }

  .spinner .rect3 {
    -webkit-animation-delay: -1.0s;
    animation-delay: -1.0s;
  }

  .spinner .rect4 {
    -webkit-animation-delay: -0.9s;
    animation-delay: -0.9s;
  }

  .spinner .rect5 {
    -webkit-animation-delay: -0.8s;
    animation-delay: -0.8s;
  }

  @-webkit-keyframes sk-stretchdelay {
    0%, 40%, 100% { -webkit-transform: scaleY(0.4) }  
    20% { -webkit-transform: scaleY(1.0) }
  }

  @keyframes sk-stretchdelay {
    0%, 40%, 100% { 
      transform: scaleY(0.4);
      -webkit-transform: scaleY(0.4);
    }  20% { 
      transform: scaleY(1.0);
      -webkit-transform: scaleY(1.0);
    }
  }

添加叠加div并与微调器同时显示。

Css将是:

.spinner_overlay {

    position: fixed;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    background-color: #fff;
    opacity: 0.2;
    z-index: 1000;
}

并添加

  

<div class="spinner_overlay"></div>

到您的模板。

这会有效!
