用html中的放大镜鼠标悬停在图像上

Question

I added a magnifying glass for images in my webpage using the following instruction: https://www.w3schools.com/howto/howto_js_image_magnifier_glass.asp

The magnified box stays on the image even if the mouse is not over it. How can I revise this in a way that the magnifying glass appears only when the mouse is over it?

Thanks,

You can do this all in CSS using hover, no need for javascript copy the style sheet from below.

<style>
* {box-sizing: border-box;}
.img-magnifier-container {
  position:relative;
  cursor:none;
}
.img-magnifier-container:hover .img-magnifier-glass {
  position: absolute;
  border: 3px solid #000;
  border-radius: 50%;
  cursor: none;
  /*Set the size of the magnifier glass:*/
  width: 100px;
  height: 100px;
  display:block;
}
.img-magnifier-glass {
  display:none;
}

</style>
