Question

我正在尝试在my site的滚动中获得更小的标题。它运行得很好，但是尽管CSS中包含了转换，但是当小标题转换为大标题（向上滚动）时，标题中的图像只能平滑过渡，反之则不然。它现在看起来有些跳跃/慌乱。

这是我的图片CSS：

标志：

.Logo.small:hover {
    background: url("images/Logo.png") no-repeat;
    background-size: contain;
    position: absolute;
    top: 8px;
    width: 40px;
    height: 40px;
    z-index: 73;
    -webkit-transition: background-image .5s;
          -webkit-transition: height 0.6s;
    -moz-transition: height 0.6s;
    transition: height 0.6s;
          -webkit-transition: width 0.6s;
    -moz-transition: width 0.6s;
    transition: width 0.6s;
}
.Logo:hover {
  background: url("images/LogoHover.png") no-repeat;
  background-size: contain;
  position: absolute;
  top: 8px;
  width: 81px;
  height: 85px;
  z-index: 70;
  -webkit-transition: background-image .5s;
}
.Logo {
    background: url("images/Logo.png") no-repeat;
    background-size: contain;
    position: absolute;
    top: 8px;
    width: 81px;
    height: 85px;
    z-index: 73;
    -webkit-transition: background-image .5s;
    -webkit-transition: width .5s;
    -webkit-transition: height .5s;
}
.Logo.small {
    background: url("images/Logo.png") no-repeat;
    background-size: contain;
    position: absolute;
    top: 8px;
    width: 40px;
    height: 40px;
    z-index: 73;
    -webkit-transition: background-image .5s;
    -webkit-transition: width .5s;
    -webkit-transition: height .5s;
}

Answer 1

因为您使用background-size来调整图片大小，而不是transform

使用

transform: scale(xx);

用于调整大小
