在CSS中使用继承

Suppose you have a table and you need to give styles to all the <TD> tags. Using inheritance to do this helps you avoid generating more content to be delivered to the client. Take this code, for example:

<table>
<td class=Cell></td>
<td class=Cell></td>
<td class=Cell></td>
</table>


This can be replaced with the following style sheet :

Table.Cell TD
{}{
  
}

<table class=Cell>
<td ></td>
<td ></td>
<td ></td>
</table>

This way, there's less code to download and it's easier to maintain.
