Question

我正在尝试设计一个简单的页面，用于仅使用 html 和 css 进行练习。我为羊角面包图像使用了悬停伪类。它可以工作，但是当我将鼠标悬停在羊角面包上时，咖啡杯图像会向右移动一点（几乎 50 或 100 像素），当我将鼠标悬停在羊角面包上时，咖啡杯将回到之前的位置。同时，我是网页设计的新手，刚开始学习几天。这是我的代码：

  margin: 0px;

  background-size: cover;
}

#img1 {
  background-repeat: no-repeat;
  width: 100%;
  height: 40%;
}

#instagram1 {
  width: 20px;
  height: 20px;
  float: left;
}

#instagram2 {
  width: 20px;
  height: 20px;
  position: relative;
  right: 168px;
  top: 5px;
}

#bakery {
  color: black;
  float: left;
  position: relative;
  bottom: 15px;
  left: 5px;
}

#cafe {
  color: black;
  float: left;
  position: relative;
  right: 75px;
  bottom: 10px;
}

div {
  width: 200px;
  height: 60px;

  background-color: #b3d9ff;
}

#croissant {

  height: 100px;
  position: relative;

  top: 250px;
}

#espresso {
  position: relative;
  top: 280px;
  right: 150px;
  width: 200px;
  height: 150px;
}

#croissant:hover {
  width: 250px;
  height: 150px;
}

Answer 1

详情：

relative
...
如果你给它一些其他的定位属性，比如 top: 10px;，它会将它的位置从通常的位置向下移动 10 个像素。
...
absolute
...
使用定位属性top、left、bottom、right 来设置位置。请记住，这些值将相对于具有相对（或绝对）定位的下一个父元素。如果没有这样的父级，它将默认一直返回到元素本身，这意味着它将相对于页面本身放置
