localeTitle: Remover classes de um elemento com jQuery
---

## Description
<section id="description"> Da mesma forma que você pode adicionar classes a um elemento com a função <code>addClass()</code> do jQuery, você pode removê-los com a função <code>removeClass()</code> do jQuery. Veja como você faria isso para um botão específico: <code>$(&quot;#target2&quot;).removeClass(&quot;btn-default&quot;);</code> Vamos remover a classe <code>btn-default</code> de todos os nossos elementos de <code>button</code> . </section>
