Answer 1

<div class="container">
  <img src="https://www.codeproject.com/KB/GDI-plus/ImageProcessing2/img.jpg" />
  <div class="overlay"></div>
</div>

而css是

img {
  width: 100px;
  height: 100px;
}
.container {
  width: 100px;
  height: 100px;
  position: relative;
  pointer-events: none;
  }
.overlay {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  background: rgba( 0, 0, 0, 0.5 );
}

Answer 2

您可以在标签后添加另一个 div。并给它CSS如下

img{
  width:100px;
  height:100px;
  
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: rgba(0,0,0,0.5);
  

}
div{
  position:absolute;
  width:50px;
  height:30px;
  cursor: not-allowed;
  top: 80px;
  left: 10px;
  right: 0;
  bottom: 0;
  background-color: grey;
  z-index: 1000;
  opacity: 0.5;
}

<img src="https://www.codeproject.com/KB/GDI-plus/ImageProcessing2/img.jpg" />
<div></div>

此外，您可以相应地调整不透明度和覆盖不可点击 div 的大小
