How to semantically provide a caption, title or label for a list in HTML

Option 1

HTML5 has the figure and figcaption elements, which I find work quite nicely.

Example:

<figure>
    <figcaption>Fruit</figcaption>
    <ul>
        <li>Apple</li>
        <li>Pear</li>
        <li>Orange</li>
    </ul>
</figure>

These are then easily styled with CSS.


Option 2

Using CSS3's ::before pseudo-element can be a nice solution:

HTML:

<ul title="Fruit">
    <li>Apple</li>
    <li>Pear</li>
    <li>Orange</li>
</ul>

CSS:

ul[title]::before {
    content: attr(title);
    /* then add some nice styling as needed, eg: */
    display: block;
    font-weight: bold;
    padding: 4px;
}

You can, of course, use a different selector than ul[title]; for example, you could add a 'title-as-header' class and use ul.title-as-header::before instead, or whatever you need.

This does have the side effect of giving you a tooltip for the whole list. If you don't want such a tooltip, you could use a data attribute instead (e.g., <ul data-title="fruit"> and ul[data-title]::before { content: attr(data-title); }).


While there is no caption or heading element structuring your markup effectively can have the same effect. Here are some suggestions:

Nested List

<ul>
    <li>
        Fruit
        <ul>
            <li>Apple</li>
            <li>Pear</li>
            <li>Organge</li>
        </ul>
    </li>
</ul>

Heading Prior to List

<hX>Fruit</hX>
<ul>
    <li>Apple</li>
    <li>Pear</li>
    <li>Orange</li>
</ul>

Definition List

<dl>
  <dt>Fruit</dt>
  <dd>Apple</dd>
  <dd>Pear</dd>
  <dd>Orange</dd>
</dl>
