title: Newer construct for width in XHTML?
body: <p>I built a table like this:</p>
  
  <pre><code>&lt;table width="100%" border="0"&gt;
      &lt;tr&gt;
          &lt;td width="20%"&gt;
              Nombre
          &lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>but I have a warning "Validation (XHTML 1.0 Transitional): Attribute 'width' is considered outdated. A newer construct is recommended"</p>
  
  <p>What is a Newer construct for width in XHTML?</p>
