Achieving Uniform Div Height within Table Cells for Background Positioning

In HTML, tables are often utilized to organize and display data. However, when attempting to fill a table cell (TD) with a DIV, achieving a consistent div height can be challenging. This article addresses this issue, exploring a practical solution to ensure that the div aligns with the bottom-right corner of its parent TD.

Consider the following HTML structure:

<table>
<tr>
<td>
<div>
<dl>
<dt>yada</dt>
<dd>yada</dd>
</dl>
</div>
</td>
<td>
<div>
<dl>
<dt>yada</dt>
<dd>yada</dd>
</dl>
</div>
</td>
</tr>
</table>

Here, the objective is to make the div expand to fully occupy the height of its corresponding TD. To achieve this:

1. Specify a height for the TD using CSS. Even a minimal height, such as 1px, will suffice.
2. Set the height of the child div as a percentage of its parent TD. By basing the div height on the parent TD, it will adjust automatically as the TD's height changes.

This approach provides a convenient solution, allowing the div to fill the TD's height and enabling precise background positioning.
