Hi there,
try:
1. Adding this HTML:
<table>
<tbody>
<tr>
<th rowspan="4"><span class="is-circle" style="background-color: #ff00bf;">Shocking Pink</span></th>
<td><strong>Hex color:</strong></td>
<td>#ff00bf</td>
</tr>
<tr>
<td><strong>RGB:</strong></td>
<td>255 0 191</td>
</tr>
<tr>
<td><strong>CMYK:</strong></td>
<td>0 100 25 0</td>
</tr>
<tr>
<td><strong>Pantone:</strong></td>
<td>PMS 806 C</td>
</tr>
</tbody>
</table>
2. Then this CSS for the circle:
.is-circle {
display: flex;
margin: auto;
width: 120px;
height: 120px;
padding: 5px;
align-items: center;
border-radius: 100%;
}
