复选框触发的可折叠动画

Question

我想知道是否有人能帮我弄个动画。我有崩溃的div，由隐藏的复选框触发。我可以动画的复选框，但div本身没有动画。我尝试过在多个类上设置转换，但没有运气，我承认，我在CSS方面并不强。有什么想法吗？提前感谢！

CSS：

body {
  font-family: "Open Sans", "Sans-serif", Arial;
  letter-spacing: 0.03em;
  padding: 5px;
  color: #435757;
}
div.main {
  width: 1000px;
  margin-left: auto;
  margin-right: auto;

}
div.content {      
  border-left: 3px solid;
  border-color: #0066cc;
  padding-left: 15px;      
  width: 95%;
  margin-left: auto;
  margin-right: auto;
}
div.labeltab {
  border-radius: 10px;
  background-color: rgba(255, 255, 255, 0.2);
  margin-top: 15px;
  margin-bottom: 15px;
}

.toggle-box {
  display: none;
}
.toggle-box + label {
  padding: 10px;
  cursor: pointer;
  display: block;
  clear: both;
  font-size: 21px;
  margin-right: auto;
  margin-bottom: 5px;
  text-align: left;
}
.toggle-box + label:hover {
  text-shadow: 1px 1px 1px rgba(0, 0, 0, 0.5);
}
.toggle-box + label + div {
  display: none;
  margin-left: 0px;
  margin-right: auto;
  -webkit-transition: all 0.5s;
  transition: all 0.5s;
}
.toggle-box:checked + label {
  color: #0066cc;
  font-style: italic;
}
.toggle-box:checked + label + div {
  display: block;
  margin-right: auto;
}
.toggle-box + label:before {
  content: "";
  display: block;
  float: left;
  font-size: 21px;
  font-weight: 300;
  border-right: 3px solid;
  border-bottom: 3px solid;
  width: 7px;
  height: 7px;
  transform: rotate(-45deg);
  margin-top: 6px;
  margin-right: 20px;
  margin-left: auto;
  text-align: left;
  -webkit-transition: all 0.5s;
  transition: all 0.5s;
}
.toggle-box:checked + label:before {
  content: "";
  color: #0066cc;
  border-right: 3px solid;
  border-bottom: 3px solid;
  width: 7px;
  height: 7px;
  transform: rotate(45deg);
  -webkit-transition: all 0.5s;
  transition: all 0.5s;
}

HTML：

<div class="LabelTab"><input class="toggle-box" id="identifier-8" name="grouped" type="checkbox"><label for="identifier-8"> Test 1</label>
<div>
<div class="content">
<h4>Content 1</h4>
<p>Stuff</p>
</div>
</div>
</div>
<div class="LabelTab"><input class="toggle-box" id="identifier-6" name="grouped" type="checkbox"><label for="identifier-6">Test 2</label>
<div>
<div class="content">
<h4>Content 2</h4>
<p>Stuff</p>
</div>
</div>
</div>

多亏了迈克尔！我在我的内容范围内设置了一个min高度和最大高度，在.：复选+ label + div中，它可以工作。现在我有多个高度，动画匹配的div。谢谢!
