Syntax

The caption must be placed immediately after the opening <table> tag:

<table>
<caption>Table title goes here</caption>
<tr>
<th>Header</th>
</tr>
<tr>
<td>Data</td>
</tr>
</table>

Key Attributes

The caption element has no specific attributes in modern HTML. The obsolete align attribute should be replaced with CSS:

  • align (obsolete) — Previously used to position the caption (top, bottom, left, right). Use CSS caption-side property instead.

To position the caption at the bottom of the table using CSS:

caption {
caption-side: bottom;
}

When to Use

Use captions for:

  • Every data table that would benefit from a title or description
  • Tables where the context or purpose may not be immediately obvious
  • Complex tables that need additional explanation
  • Tables that are referenced in surrounding text

Best practices:

  • Keep captions concise but descriptive
  • The caption should describe what the table contains, not how to read it
  • You can include additional context using nested elemens lique <small>
  • Only one caption is allowed per table

Captions significantly improve table accessibility. Screen readers announce the caption before reading table data, helping users decide if they want to explore the table’s content.
