如何使用伪 CSS 转换更改活动切换按钮的 CSS

Question

我的网页上有多个切换按钮。我正在使用 checkbox 输入控件和一些 CSS 来获得 material 切换按钮设计。当我更改任何切换按钮的状态时，CSS 效果会反映在第一个切换按钮上。我怎样才能只在活动切换上应用效果。

<div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle" name="toggle" checked=true class="switch" />
    <label for="toggle" class=""></label>
  </div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle" name="toggle" checked=true class="switch" />
    <label for="toggle" class=""></label>
  </div>
</div>

这是我正在使用的 CSS。

.material-toggle {
  height: 22px;
  width: 40px;
  margin: 12px;
}

.material-toggle input:empty {
    margin-left: -9999px;
}

.material-toggle input:empty ~ label {
    position: relative;
    float: left;
    width: 150px;
    cursor: pointer;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

.material-toggle input:empty ~ label:before, 
.material-toggle input:empty ~ label:after {
  position: absolute;
    display: block;
  content: ' ';
  -webkit-transition: all 250ms cubic-bezier(.4,0,.2,1);
  transition: all 250ms cubic-bezier(.4,0,.2,1);
}

.material-toggle input:empty ~ label:before {
    top: 3px;
    left: 0px;
    width: 32px;
    height: 13px;
    border-radius: 12px;
    background-color: #bdbdbd;
}

input.switch:empty ~ label:after {
    top: -1px;
    left: -9px;
    width: 1.4em;
    height: 8px;
    bottom: 0.1em;
    margin-left: 0.1em;
    background-color: #fff;
    border-radius: 50%;
    width: 17px;
    height: 17px;
    border-radius: 50%;
    border: solid 2px;
    border-color: #fff;
    box-shadow: 0 3px 4px 0 rgba(0,0,0,.14),0 3px 3px -2px rgba(0,0,0,.2),0 1px 8px 0 rgba(0,0,0,.12);
}

.material-toggle input:checked ~ label:before {
    background-color: #1e88e5;
}

.material-toggle input:checked ~ label:after {
    left: 15px;
  background-color: #1565c0;
  border-color: #1565c0;
}

我附上了 codepen 同样的。

Answer 1

您需要唯一的 ID，目前它们都有 id="toggle"

<div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle" name="toggle" checked=true class="switch" />
    <label for="toggle" class=""></label>
  </div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle2" name="toggle" checked=true class="switch" />
    <label for="toggle2" class=""></label>
  </div>
</div>

Answer 2

如果你想有多个切换按钮，你需要使用ID，但是你在两个切换中有相同的ID，这是不可能发生的，因为ID是唯一的，所以改变ID和label for 以定位这些 ID。

.material-toggle {
  height: 22px;
  width: 40px;
  margin: 12px;
}
.material-toggle input:empty {
  margin-left: -9999px;
}
.material-toggle input:empty ~ label {
  position: relative;
  float: left;
  width: 150px;
  cursor: pointer;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}
.material-toggle input:empty ~ label:before,
.material-toggle input:empty ~ label:after {
  position: absolute;
  display: block;
  content: ' ';
  -webkit-transition: all 250ms cubic-bezier(.4, 0, .2, 1);
  transition: all 250ms cubic-bezier(.4, 0, .2, 1);
}
.material-toggle input:empty ~ label:before {
  top: 3px;
  left: 0px;
  width: 32px;
  height: 13px;
  border-radius: 12px;
  background-color: #bdbdbd;
}
input.switch:empty ~ label:after {
  top: -1px;
  left: -9px;
  width: 1.4em;
  height: 8px;
  bottom: 0.1em;
  margin-left: 0.1em;
  background-color: #fff;
  border-radius: 50%;
  width: 17px;
  height: 17px;
  border-radius: 50%;
  border: solid 2px;
  border-color: #fff;
  box-shadow: 0 3px 4px 0 rgba(0, 0, 0, .14), 0 3px 3px -2px rgba(0, 0, 0, .2), 0 1px 8px 0 rgba(0, 0, 0, .12);
}
.material-toggle input:checked ~ label:before {
  background-color: #1e88e5;
}
.material-toggle input:checked ~ label:after {
  left: 15px;
  background-color: #1565c0;
  border-color: #1565c0;
}

<div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle" name="toggle" checked=true class="switch" />
    <label for="toggle" class=""></label>
  </div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle2" name="toggle" checked=true class="switch" />
    <label for="toggle2" class=""></label>
  </div>
</div>

Answer 3

<div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle" name="toggle"  class="switch" />
    <label for="toggle" class=""></label>
  </div>
  <div class="material-toggle">
    <input type="checkbox" id="toggle-2" name="toggle" class="switch" />
    <label for="toggle-2" class=""></label>
  </div>
</div>

我解决了为值分配不同标签的 。我做了一个 material-主题切换器，但我使用了 Javascript 和 Jquery 来让它在一个页面中使用多个切换器。

Answer 4

你为什么不使用不同的 "id"。如果我理解这个问题，答案是：

<div>
    <div class="material-toggle">
        <input type="checkbox" id="toggle1" name="toggle" checked=true class="switch" />
        <label for="toggle1" class=""></label>
    </div>
    <div class="material-toggle">
        <input type="checkbox" id="toggle2" name="toggle" checked=false class="switch" />
        <label for="toggle2" class=""></label>
    </div>
</div>
