带列的 HTML 无序列表

mon*_*jbl 1 html css html-lists

我想将我的无序列表格式化为两部分文本。我一直在尝试找出如何使用 Google 执行此操作。但是每个人似乎都对让他们的列表从左向右流动感兴趣,这不是我想要做的。我正在寻找的是一种进行以下操作的方法:

 Food                Calories

 Fruit
    -Apple            90
    -Grape            5
    -Berries          
       -Strawberry    16
       -Blueberry     9
 Vegetable
    -Cucumber         12
    -Onions            
       -Red           29
       -White         34
       -Vidalia       47

这可以使用无序列表和 CSS 实现吗?我不想为此使用表格,因为我想进行<li>扩展和收缩。

编辑:希望它现在看起来更像是一个扩展/合同层次结构,而不是严格的表格数据。我知道可以用表格来做到这一点,但以这种方式呈现层次结构似乎不太自然。

使用以下 HTML 您可以做到这一点(坦率地说,使用其他HTML 您可以做到这一点......)但您应该使用表格。

无论如何,也就是说,我正在使用的 HTML:

<ul>
    <li class="head">
        <span class="col1">Food</span>
        <span class="col2">Calories</span>
    </li>
    <li>Fruits
        <ul>
            <li>
                <span class="col1">Apple</span>
                <span class="col2">90</span>
            </li>
            <li>
                <span class="col1">Grape</span>
                <span class="col2">5</span>

            <li>

                <span class="col2">16</span>

为了允许键盘导航,并显示嵌套的食物/卡路里值以响应选项卡事件,我对 HTML 进行了一些修改,以使用元素包装fruits和vegetable文本a:

<ul>
    <li class="head">
        <span class="col1">Food</span>
        <span class="col2">Calories</span>
    </li>
    <li><a href="#">Fruits</a>
        <ul>
            <li>
                <span class="col1">Apple</span>
                <span class="col2">90</span>
            </li>
            <li>
                <span class="col1">Grape</span>
                <span class="col2">5</span>

然而,这两种方法都假设您想自动隐藏,并根据用户交互显示。如果该假设不正确,则不需要转换。

顺便提一下,一个类似手风琴的table解决方案:

<table>
    <colgroup>
        <col class="foods" />
        <col class="calories" />
    </colgroup>
    <thead>
        <tr>
            <th>Food</th>
            <th>Calories</th>
        </tr>

        <tr class="header">
            <td colspan="2">Fruits</td>
        </tr>
        <tr>
            <td>Apple</td>
            <td>90</td>

这与之前的假设相同,即您希望通过将鼠标悬停在标题上以显示隐藏内容来控制可见性。

而且,只是为了踢球,tab使用元素tabindex上的属性添加键盘导航(使用)tr.header:

<table>
    <colgroup>
        <col class="foods" />
        <col class="calories" />
    </colgroup>
    <thead>
        <tr>
