HTML <data> tagS2C Home   « HTML <data> tag

Definition

The <data> tag is used for showing human-readable content along with a value that is machine-readable.

The <data> tag was introduced in HTML5.

Example


<table>
  <tr>
    <th>Fruit</th>
    <th>Colour</th>
    <th>Quantity</th>
  </tr>
  <tr>
    <td><data value="11111">Banana</data><td>
    <td>Yellow</td>
    <td>5</td>
  </tr>
  <tr>
    <td><data value="22222">Pea</data><td>
    <td>Green</td>
    <td>50</td>
  </tr>
</table>
Fruit Colour Quantity
Banana Yellow 5
Pea Green 50

In the example above we are giving each fruit a machine readable number via the <data> tag; this could for example be a stock number that a script could use for doing some processing on a particular kind of fruit.
