html - 单击复选框有时会切换其他复选框

Question

所以我得到了 5 个 checkbox。一个比一个低。它们是使用 svg 和 polyline 制作的。当我点击每个复选框的标签时，它会切换到正确的复选框，但当我点击复选框的图像时，它有时会切换到不正确的复选框!

.cbx {
  margin: auto;
  margin-top: 2px;
  -webkit-user-select: none;
  user-select: none;
  cursor: pointer;
}
.cbx span {
  display: inline-block;
  vertical-align: middle;
  transform: translate3d(0, 0, 0);
}
.cbx span:first-child {
  position: relative;
  width: 18px;
  height: 18px;
  border-radius: 3px;
  transform: scale(1);
  vertical-align: middle;
  border: 1px solid #9098A9;
  transition: all 0.2s ease;
}
.cbx span:first-child svg {
  position: absolute;
  top: 3px;
  left: 2px;
  fill: none;
  stroke: #FFFFFF;
  stroke-width: 2;
  stroke-linecap: round;
  stroke-linejoin: round;
  stroke-dasharray: 16px;
  stroke-dashoffset: 16px;
  transition: all 0.3s ease;
  transition-delay: 0.1s;
  transform: translate3d(0, 0, 0);
}
.cbx span:first-child:before {
  content: "";
  width: 100%;
  height: 100%;
  background: #506EEC;
  display: block;
  transform: scale(0);
  opacity: 1;
  border-radius: 50%;
}
.cbx span:last-child {
  padding-left: 8px;
}
.cbx:hover span:first-child {
  border-color: #506EEC;
}

.inp-cbx:checked + .cbx span:first-child {
  background: #506EEC;
  border-color: #506EEC;
  animation: wave 0.4s ease;
}
.inp-cbx:checked + .cbx span:first-child svg {
  stroke-dashoffset: 0;
}
.inp-cbx:checked + .cbx span:first-child:before {
  transform: scale(3.5);
  opacity: 0;
  transition: all 0.6s ease;
}

@keyframes wave {
  50% {
    transform: scale(0.9);
  }
}

选择复选框 1、2、3、4。然后单击复选框 3 取消选中它。取而代之的是取消选中复选框 4。再次单击复选框 3 后，它会取消选中。

因为 transform: scale(3.5) 在检查时会扩大它的大小并覆盖其他复选框，这就是为什么..

.inp-cbx:checked + .cbx span:first-child:before {
  transform: scale(1); // set scale to it's actual size instead of 3.5
  opacity: 0;
  transition: all 0.6s ease;
}

.cbx {
  margin: auto;
  margin-top: 2px;
  -webkit-user-select: none;
  user-select: none;
  cursor: pointer;
}
.cbx span {
  display: inline-block;
  vertical-align: middle;
  transform: translate3d(0, 0, 0);
}
.cbx span:first-child {
  position: relative;
  width: 18px;
  height: 18px;
  border-radius: 3px;
  transform: scale(1);
  vertical-align: middle;
  border: 1px solid #9098A9;
  transition: all 0.2s ease;
}
.cbx span:first-child svg {
  position: absolute;

.cbx span:last-child {
