Responsive Table with Pure CSS

A minimalist pure CSS solution to create a mobile-friendly responsive table that uses CSS media queries to make table cells full width on small devices.

How to use it:

Use data-label attribute to specify the group headers for table cells.

<table>
  <thead>
    <tr>
      <th>Payment</th>
      <th>Issue Date</th>
      <th>Amount</th>
      <th>Period</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td data-label="Payment">Payment #1</td>
      <td data-label="Issue Date">02/01/2015</td>
      <td data-label="Amount">$2,311</td>
      <td data-label="Period">01/01/2015 - 01/31/2015</td>
    </tr>
    <tr>
      <td data-label="Payment">Payment #2</td>
      <td data-label="Issue Date">03/01/2015</td>
      <td data-label="Amount">$3,211</td>
      <td data-label="Period">02/01/2015 - 02/28/2015</td>
    </tr>
  </tbody>
</table>

table {
  border: 1px solid #ccc;
  width: 100%;
  margin: 0;
  padding: 0;
  border-collapse: collapse;
  border-spacing: 0;
}
table tr {
  border: 1px solid #ddd;
  padding: 5px;
}
table th,
table td {
  padding: 10px;
  text-align: center;

table thead { display: none; }
table tr {

  display: block;
  text-align: right;
  font-size: 13px;
  border-bottom: 1px dotted #ccc;
}
table td:last-child { border-bottom: 0; }
table td:before {
  content: attr(data-label);
  float: left;
  text-transform: uppercase;
  font-weight: bold;
}
