I have some data that I'm reading from JSON and writing into a Table.
Currently looks like following.
<table>
<tr><td>Feature 1</td><td>true</td><td>false</td></tr>
<tr><td>Feature 2</td><td>false</td><td>false</td></tr>
<tr><td>Feature 3</td><td>true</td><td>true</td></tr>
</table>
What I want to do is leave the true/false data as it is but use CSS to turn the data into Tick/Cross or smiley / frown images.
I thing I have seen CSS3 notation for this, but I can't find it.
