localeTitle: Criar um botão de bootstrap de elemento de bloco
---

## Description
<section id="description"> Normalmente, seus elementos de <code>button</code> com as classes <code>btn</code> e <code>btn-default</code> são tão largos quanto o texto que eles contêm. Por exemplo: <code>&lt;button class=&quot;btn btn-default&quot;&gt;Submit&lt;/button&gt;</code> Esse botão seria tão largo quanto a palavra &quot;Enviar&quot;. <button class="btn btn-default">Enviar</button> Ao torná-los elementos de bloco com a classe adicional de <code>btn-block</code> , seu botão se estenderá para preencher todo o espaço horizontal de sua página e todos os elementos seguintes irão fluir para uma &quot;nova linha&quot; abaixo do bloco. <code>&lt;button class=&quot;btn btn-default btn-block&quot;&gt;Submit&lt;/button&gt;</code> Esse botão ocuparia 100% da largura disponível. <button class="btn btn-default btn-block">Enviar</button> Observe que esses botões ainda precisam da classe <code>btn</code> . Adicione a classe <code>btn-block</code> Bootstrap ao seu botão Bootstrap. </section>

    testString: 'assert($("button").hasClass("btn-block"), "Your button should have the class <code>btn-block</code>.");'
  - text: Certifique-se de que todos os seus elementos de <code>button</code> tenham uma tag de fechamento.
    testString: 'assert(code.match(/<\/button>/g) && code.match(/<button/g) && code.match(/<\/button>/g).length === code.match(/<button/g).length, "Make sure all your <code>button</code> elements have a closing tag.");'
