How Can I Make a DIV Element Fill an Entire Table Cell Using Modern CSS?

Ensuring a DIV Spans an Entire Table Cell with Modern CSS

In the past, it has been a challenge to create a DIV that seamlessly fills an entire table cell without precise knowledge of the cell's dimensions. With the advent of CSS3, however, a simple and elegant solution has emerged.

To fill a DIV to the entirety of a table cell, both the cell's width and height must be inherited. This can be achieved by setting the height of the parent row (TR) to a small, arbitrary value, such as "1px," and setting the height of the table cell (TD) to "inherit."

Finally, the DIV within the table cell can be set to "height: 100%." This ensures that the DIV expands to the full height and width of the cell.

Here's an example of how to implement this solution:

By following this approach, you can easily create a DIV that spans the entirety of a table cell, regardless of its unknown dimensions. This technique is compatible with modern browsers, such as IE Edge and Chrome, providing a robust and flexible solution to a lingering CSS challenge.
