HTML-CSS: Tips of the Day

How to center the contents of an HTML table?

Here is an example with CSS and inline style attributes:

HTML Code:

<table border="1">
    <tr>
        <td style="text-align: center; vertical-align: middle;">Text</td>
        <td style="text-align: center; vertical-align: middle;">Text</td>
    </tr>
</table>

<table border="1" id="cssTable">
    <tr>
        <td>Text</td>
        <td>Text</td>
    </tr>
</table>

CSS Code:

td 
{
    height: 50px; 
    width: 50px;
}

#cssTable td 
{
    text-align: center; 
    vertical-align: middle;
}

EDIT: The valign attribute is deprecated in HTML5 and should not be used.
