手风琴菜单上的旋转箭头

Question

全新的这里和一个全新的新手，所以请原谅我的多重失礼，我承诺。我正试图为一个具有可扩展信息的iBook制作一个小部件。考虑到空间有限，试着用手风琴来做。通过多次迭代(有些只是CSS，另一些使用CSS+jQuery)，我已经登陆到下面，我很高兴，除了不能得到正确旋转的第二个箭头。是否可以使用无线电/检查方法？

我的代码在下面(小提琴拉链)

CSS:

body {
font-family:’Arial’, sans-serif;      
}

.accordion {
margin: 0 auto;
width: 400px;
}

.accordion > label {
display: block;

}

.rotate {
   padding:0;
  margin:-2px 0 0 0px;
  line-height:20px;
  width:13px;
  position:absolute;

   transition: all 1s ease;
 -o-transition: all 1s ease;
 -moz-transition: all 1s ease;
 -webkit-transition: all 1s ease;
 }

.accordion > input {
display: none;
}

.accordion > div {
max-height: 0;
overflow: hidden;
}

.accordion > input:checked + label + div {
max-height: 500px;
}

.accordion > div > * {
margin: 10px;
}

.accordion > input:checked + label {
background-color: rgba(19,14,109,0.21);
}


.accordion > label {
background-color: rgba(19,14,109,0.08);
border: 1px solid gray;
color: black;
cursor: pointer;
font-weight: bold;
padding: 4px 10px;

}

.accordion > div {

 border-bottom: 1px solid gray; 
 border-left: 1px solid gray; 
border-right: 1px solid gray; 
-webkit-transition: all ease-in-out 1000ms;
-moz-transition: all ease-in-out 1000ms;
-o-transition: all ease-in-out 1000ms;
transition: all ease-in-out 1000ms;
}

input[name='accordion1'] ~ .rotate {
 transform: rotate(0deg);
 -o-transform: rotate(0deg);
 -ms-transform: rotate(0deg);
 -webkit-transform: rotate(0deg);
 } 

input[name='accordion1']:checked ~ label .rotate {
 transform: rotate(90deg);
 -o-transform: rotate(90deg);
 -ms-transform: rotate(90deg);
 -webkit-transform: rotate(90deg);
 }

<div class="accordion">
 <input id="acrd1-item1" name="accordion1" type="radio"checked>
     <label for="acrd1-item1"><div class="rotate">&#9654;</div>&nbsp &nbsp Common ICU Sedatives</label>

Answer 1

只需将第二个块放置在div.accordian中，如下所示：

<div class="accordion">
  <input id="acrd1-item1" name="accordion1" type="radio"checked>
  ...
</div>

<div class="accordion">
  <input id="acrd1-item2" name="accordion1" type="radio">
  ...
</div>

之后就像魔法一样工作了。下面是更新的小提琴
