  </tr>
  <tr>
   <td>Tag omission</td>
   <td>None, both, o inicio da tag e o final da tag são obrigatórios.</td>

<h2 id="Atributos">Atributos</h2>

<p>Como todos os outros elementos HTML, este elemento possui os <a href="/en/HTML/Global_attributes" rel="internal">atributos globais</a>.</p>

<dl>
 <dt>{{ htmlattrdef("form") }}</dt>
 <dd>This attribute specifies the form which the <code>progress</code> element belongs to.</dd>
 <dt>{{ htmlattrdef("max") }}</dt>
 <dd>This attribute describes how much work the task indicated by the <code>progress</code> element requires.</dd>
 <dt>{{ htmlattrdef("value") }}</dt>
 <dd>This attribute specifies how much of the task that has been completed. If there is no <code>value</code> attribute, the progress bar is indeterminate; this indicates that an activity is ongoing with no indication of how long it is expected to take.</dd>
</dl>

<p>You can use the {{ cssxref("orient") }} property to specify whether the progress bar should be rendered horizontally (the default) or vertically. The {{ cssxref(":indeterminate") }} pseudo-class can be used to match against indeterminate progress bars.</p>
