Newer construct for width in XHTML?

Question

I built a table like this:

<table width="100%" border="0">
    <tr>
        <td width="20%">
            Nombre
        </td>
    </tr>
</table>

but I have a warning "Validation (XHTML 1.0 Transitional): Attribute 'width' is considered outdated. A newer construct is recommended"

What is a Newer construct for width in XHTML?

Answer 1

The width attribute for <td> has been deprecated.

You should replace the width attribute with the CSS width property:

<table width="100%" border="0">
    <tr>
        <td style="width: 20%;">
            Nombre
        </td>
    </tr>
</table>

Answer 2

Use only CSS attributes:

<table style="width:100%; border:0px;">
    <tr>
        <td style="width:20%;">
            Nombre
        </td>
    </tr>
</table>
