html - 如何将一张图片放在另一张图片上？

Question

我想在我的背景上放一个标志，但当我缩小和放大时它总是滑落。

.top {
  height: 563px;
  width: 1000px;
  display: block;
  margin-left: auto;
  margin-right: auto;
}

.logo {
  position: absolute;
  top: 20px;
  left: 800px;
}

<div class="toplogo">
  <img src="css/elefant.png" class="top">
  <img src="css/logo.png" class="logo">
</div>

你必须使用z-index。我很快做了一个例子。你也可以尝试第二个想法。对于缩放问题，您必须使用 '%' 而不是 'px'希望对您有所帮助

.top {
  position: absolute;
  left: 0px;
  top: 0px;
  z-index: -1;
}

.logo {
  position: absolute;
  left: 325px;
  top: 150px;
  z-index: 0;
}

<div>
  <img src="https://img.purch.com/rc/696x392/aHR0cDovL3d3dy5saXZlc2NpZW5jZS5jb20vaW1hZ2VzL2kvMDAwLzEwNS83OTIvb3JpZ2luYWwvc2h1dHRlcnN0b2NrXzM3MTM5NjAxNy5qcGc=" width="700px" class="top">

.header {

  width: 100%;
  Height: 400px;
  background-position: center; /* Center the image */
  background-repeat: no-repeat; /* Do not repeat the image */
  background-size: cover; /* Resize the background image to cover the entire container */

.logo {
margin: 150px 42.5%
