# --description--

Font Awesome é uma biblioteca conveniente de ícones. Estes ícones podem ser fontes da web ou gráficos vetoriais. Estes ícones são tratados assim como as fontes. Você pode especificar seu tamanho utilizando pixels, e eles irão assumir o tamanho de fonte de seus elementos HTML parentes.

Você pode incluir o Font Awesome em qualquer aplicativo, adicionando o seguinte código ao topo do seu HTML:

```html
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css" integrity="sha384-50oBUHEmvpQ+1lW4y57PTFmhCaXp0ML5d60M1M7uH2+nqUivzIebhndOJK28anvf" crossorigin="anonymous">
```

Neste caso, já o adicionamos para você a esta página por trás dos panos.

O elemento `i` foi usado originalmente para fazer outros elementos itálicos, mas agora é comumente usado para ícones. Você pode adicionar as classes Font Awesome ao elemento `i` para transformá-lo em um ícone, por exemplo:

```html
<i class="fas fa-info-circle"></i>
```

Observe que o elemento `span` também é aceitável para uso com ícones.

# --instructions--

Use o Font Awesome para adicionar um ícone `thumbs-up` ao botão like, doando-o um elemento `i` com as classes `fas` e `fa-thumbs-up`. Certifique-se de manter o texto `Like` ao lado do ícone.

# --hints--

Você deve adicionar um elemento `i` com as classes `fas` e `fa-thumbs-up`.

```js
assert($('i').is('.fas.fa-thumbs-up') || $('span').is('.fas.fa-thumbs-up'));
```

O ícone `fa-thumbs-up` deve estar localizado dentro do botão Like.

```js
assert(
  ($('i.fa-thumbs-up').parent().text().match(/Like/gi) &&
    $('.btn-primary > i').is('.fas.fa-thumbs-up')) ||
    ($('span.fa-thumbs-up').parent().text().match(/Like/gi) &&
      $('.btn-primary > span').is('.fas.fa-thumbs-up'))
);
```

O elemento `i` deve estar dentro do novo elemento `button`.

```js
assert(
  $('button').children('i').length > 0 ||
    $('button').children('span').length > 0
);
```

O elemento de ícone deve ter uma tag de fechamento.

```js
assert(code.match(/<\/i>|<\/span>/g));
```
