Question

BiPredicate

.arrow {
  display: inline-block;
  height: 8px;
  width: 8px;
  margin-top: 20px;
  border-top: solid black 2.5px;
  border-left: solid black 2.5px;
  -ms-transform: rotate(-45deg);
  -webkit-transform: rotate(-45deg);
  transform: rotate(-45deg);
  -webkit-transition: transform 1s;
  -moz-transition: transform 1s;
  transition: transform 1s;
  cursor: pointer;
}
.arrow::before {
  content: "";
  display: inline-block;
  width: 18px;
  margin-left: -3px;
  margin-bottom: 7px;
  border-top: solid black 1.8px;
  -ms-transform: rotate(45deg);
  -webkit-transform: rotate(45deg);
  transform: rotate(45deg);
}
.arrow:hover {
  -ms-transform: scale(1.2);
  -webkit-transform: scale(1.2);
  -moz-transform: scale(1.2);
  transform: scale(1.2);
}

我使用css绘制一个箭头，并尝试使用css：hover和transform：scale创建一个悬停放大效果。但是，代码首先旋转箭头，然后再将其放大。我想知道为什么旋转发生，我该如何解决？提前致谢！

Answer 1

将此CSS用于悬停：

.arrow:hover {
  -ms-transform: scale(1.2) rotate(-45deg);
  -webkit-transform: scale(1.2) rotate(-45deg);
  -moz-transform: scale(1.2) rotate(-45deg);
  transform: scale(1.2) rotate(-45deg);
}

旋转已在整个元素上设置，并且在悬停变换期间未计算。

here是一个有效的例子

.arrow {
  display: inline-block;
  height: 8px;
  width: 8px;
  margin-top: 20px;
  border-top: solid black 2.5px;
  border-left: solid black 2.5px;
  -ms-transform: rotate(-45deg);
  -webkit-transform: rotate(-45deg);
  transform: rotate(-45deg);
  -webkit-transition: transform 1s;
  -moz-transition: transform 1s;
  transition: transform 1s;
  cursor: pointer;
}
.arrow::before {
  content: "";
  display: inline-block;
  width: 18px;
  margin-left: -3px;
  margin-bottom: 7px;
  border-top: solid black 1.8px;
  -ms-transform: rotate(45deg);
  -webkit-transform: rotate(45deg);
  transform: rotate(45deg);
}
.arrow:hover {
  -ms-transform: rotate(-45deg) scale(1.2);
  -webkit-transform: rotate(-45deg) scale(1.2);
  -moz-transform: rotate(-45deg) scale(1.2);
  transform: rotate(-45deg) scale(1.2);
}

<span class="arrow"></span>

问题是转换属性不总结，如果覆盖属性并希望保留它的原始值，则需要重复它。

Answer 3

您只能将转换提供给:before，以便在悬停时不会旋转。

.arrow {
  display: inline-block;
  height: 1px;
  width: 18px;
  border-top: solid black 1.8px;
  -webkit-transition: transform 1s;
  -moz-transition: transform 1s;
  transition: transform 1s;
  cursor: pointer;
}
.arrow:before {
  content: "";
  display: inline-block;
  margin-top: -10px;
  height: 8px;
  width: 8px;
  border-top: solid black 2.5px;
  border-left: solid black 2.5px;
  -ms-transform: rotate(-45deg);
  -webkit-transform: rotate(-45deg);
  transform: rotate(-45deg);
  -webkit-transition: transform 1s;
  -moz-transition: transform 1s;
  transition: transform 1s;
  cursor: pointer;
position: relative;
top: -9px;
}
.arrow:hover {
  -ms-transform: scale(1.2);
  -webkit-transform: scale(1.2);
  -moz-transform: scale(1.2);
  transform: scale(1.2);
}

<span class="arrow"></span>

CSS：hover变换缩放命令旋转对象
