如何为HTML/CSS切换按钮的BN/EN选项添加跳转链接

要实现点击BN跳转至google.com、点击EN跳转至facebook.com的需求，你需要调整HTML结构并修改对应的CSS样式，具体步骤如下：

1. 修改HTML结构 #

将原来的<span>标签替换为<a>标签，添加对应的跳转链接：

<div class="switch">
  <input
    id="language-toggle"
    class="check-toggle check-toggle-round-flat"
    type="checkbox"
  />
  <label for="language-toggle"></label>
  <a href="https://google.com" class="on">BN</a>
  <a href="https://facebook.com" class="off">EN</a>
</div>

2. 调整CSS样式 #

由于原来的样式针对<span>标签，且设置了pointer-events: none（禁止点击），需要修改选择器并移除该属性，确保链接可点击：

.switch {
  position: relative;
  display: inline-block;
  margin: 0 5px;
}

/* 将选择器从span改为a，移除pointer-events: none */
.switch > a {
  position: absolute;
  top: 14px;
  font-family: 'Helvetica', Arial, sans-serif;
  font-weight: bold;
  font-size: 12px;
  text-transform: uppercase;
  text-shadow: 0 1px 0 rgba(0, 0, 0, .06);
  width: 50%;
  text-align: center;
  color: inherit;
  text-decoration: none; /* 移除链接默认下划线 */
}

input.check-toggle-round-flat:checked ~ .off {
  color: #F36F25;
}

input.check-toggle-round-flat:checked ~ .on {
  color: #fff;
}

.switch > a.on {
  left: 0;
  padding-left: 2px;
  color: #F36F25;
}

.switch > a.off {
  right: 0;
  padding-right: 4px;
  color: #fff;
}

.check-toggle {
  position: absolute;
  margin-left: -9999px;
  visibility: hidden;
}
.check-toggle + label {
  display: block;
  position: relative;
  cursor: pointer;
  outline: none;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

input.check-toggle-round-flat + label {
  padding: 2px;
  width: 97px;
  height: 35px;
  background-color: #F36F25;
  -webkit-border-radius: 60px;
  -moz-border-radius: 60px;
  -ms-border-radius: 60px;
  -o-border-radius: 60px;
  border-radius: 60px;
}
input.check-toggle-round-flat + label:before, input.check-toggle-round-flat + label:after {
  display: block;
  position: absolute;
  content: "";
}

input.check-toggle-round-flat + label:before {
  top: 2px;
  left: 2px;
  bottom: 2px;
  right: 2px;
  background-color: #F36F25;
  
  -moz-border-radius: 60px;
  -ms-border-radius: 60px;
  -o-border-radius: 60px;
  border-radius: 60px;
}
input.check-toggle-round-flat + label:after {
  top: 4px;
  left: 4px;
  bottom: 4px;
  width: 48px;
  background-color: #fff;
  -webkit-border-radius: 52px;
  -moz-border-radius: 52px;
  -ms-border-radius: 52px;
  -o-border-radius: 52px;
  border-radius: 52px;
  -webkit-transition: margin 0.2s;
  -moz-transition: margin 0.2s;
  -o-transition: margin 0.2s;
  transition: margin 0.2s;
}

input.check-toggle-round-flat:checked + label {
}

input.check-toggle-round-flat:checked + label:after {
  margin-left: 44px;
}

关键改动说明 #

• 将<span>替换为<a>标签，直接添加跳转链接，符合HTML语义化规范
• 移除了.switch > span中的pointer-events: none属性，确保链接可以被点击
• 为<a>标签添加text-decoration: none和color: inherit，保持原有的视觉样式，避免链接默认下划线和颜色干扰
• 所有针对<span>的CSS选择器替换为<a>，保证样式正常生效
