Add sorting arrows to <th> like table sorter

The best solution without images, pure CSS. Just put the classnames headerSortDown and headerSortUp on the td or th rows and the caret will appear.

table td,
table th {
  border: 1px solid silver;
}

.headerSortDown:after,
.headerSortUp:after {
  content: ' ';
  position: relative;
  left: 2px;
  border: 8px solid transparent;
}

.headerSortDown:after {
  top: 10px;
  border-top-color: silver;
}

.headerSortUp:after {
  bottom: 15px;
  border-bottom-color: silver;
}

.headerSortDown,
.headerSortUp {
  padding-right: 10px;
}
<table>
  <thead>
    <tr>
      <th class="headerSortDown">ID</th>
      <th class="headerSortUp">Username</th>
      <th>Fullname</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>1</td>
      <td>John</td>
      <td>John Doe</td>
    </tr>
    <tr>
      <td>2</td>
      <td>Jenny</td>
      <td>Jenny Smith</td>
    </tr>
    <tr>
      <td>3</td>
      <td>Tom</td>
      <td>Tom Doe</td>
    </tr>
  </tbody>
</table>

UPDATE: Fixed for chrome


I get invalid property value in chrome.

With quotes it works:

background: url("data:image/gif;base64, R0lGODlhFQAJAIAAACMtMP///yH5BAEAAAEALAAAAAAVAAkAAAIXjI+AywnaYnhUMoqt3gZXPmVg94yJVQAAOw=") no-repeat 99%;

I converted the double arrow to base64, too.
