Question

我正在使用下面的HTML显示标签列表（我通过专注于最长的列表来简化它，因为这是导致我的问题的那个）。如何进行制作，以便div包含ul的{{1}}根据ul的长度自动扩展到其高度。 CSS低于HTML：

<div class="col-lg-offset-2 col-lg-8">
    <section class="tabs">
        <h2 class="centered">SAMPLE MENU</h2>
        <input id="tab-1" type="radio" name="radio-set" class="tab-selector-1"     checked="checked"    />
        <label for="tab-1" class="tab-label-1">Casual Eating</label>
        <input id="tab-2" type="radio" name="radio-set" class="tab-selector-2" />
        <label for="tab-2" class="tab-label-2">Dining</label>
        <input id="tab-3" type="radio" name="radio-set" class="tab-selector-3" />
        <label for="tab-3" class="tab-label-3">Afternoon Tea</label>
        <input id="tab-4" type="radio" name="radio-set" class="tab-selector-4" />
        <label for="tab-4" class="tab-label-4">Desserts</label>
        <div class="clear-shadow"></div>
        <div class="content">
            <div class="content-2">
                <ul class="menu_items">

Answer 1

我已经更新了示例（抱歉，没有意识到其他人不会再看到原始代码 - 我第一次使用jsfiddle）。

我不得不做各种改变：

删除＆＃34; .content＆＃34;的硬编码高度（让浏览器计算它）
删除＆＃34; .content div＆＃34;的绝对定位（不清楚你为什么需要它）
最重要的是为＆＃34; .content添加了一条规则：＆＃34; （这通常用于在CSS中定义clearfix类，并在适当的元素上使用它

.content：after { 内容：＆＃34; ＆＃34 ;; 显示：块; font-size：0; 身高：0; 明确：两者; 能见度：隐藏; }

现在背景延伸到列表的底部

Answer 2

我会在你的css中改变你的3件事：

首先删除位置：绝对;来自.content div {}
移除高度：370px;来自.content {}
替换＆＃39; float：left＆＃39;显示：inline-block for .menu_items li {}

- Your fiddle updated

这些元素的更新css将是：

.content {
    position: relative;
    width: 100%;
    z-index: 5;
    border-radius: 0 3px 3px 3px;
}

.content div {
    padding: 10px 40px;
    z-index: 1;
    opacity: 0;
    -webkit-transition: opacity linear 0.1s;
    -moz-transition: opacity linear 0.1s;
    -o-transition: opacity linear 0.1s;
    -ms-transition: opacity linear 0.1s;
    transition: opacity linear 0.1s;
}
.menu_items li{
    display:inline-block;
    width:340px;
}
