我在 Angular2 中有一个iframe
,根据透明图片的大小调整其height
和width
。在iframe
内部指定的URL加载之前,我想显示一个微调器图标,但它隐藏在透明图像后面。如何将图标放在该图像上?
这是我的HTML代码:
<div class="wrapper" *ngIf = "showIframe" id="feedsIframe" >
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12" class="h_iframe">
<section class="widget" widget>
<div class="widget-body">
<div class="loader animated fadeIn handle" id="spinner007">
<span class="spinner">
<i class="fa fa-spinner fa-spin"></i>
</span>
</div>
</div>
</section>
<img class="ratio" src="assets/img/pictures/transparent2.png">
<iframe class="embed-responsive-item" scrolling="yes" frameborder="0" allowfullscreen [src]="iframeURL" allowfullscreen >
</iframe>
<a (click) = "goBack()" class="button">
<span style="color: #555;" >BACK</span>
</a>
</div>
</div>
