--description--

Você tem adicionado atributos de id ou class aos elementos que você deseja especificamente estilizar. Eles são conhecidos como ID e seletores de classe. Existem outros seletores CSS que você pode usar para selecionar grupos de elementos para estilizar.

Vamos usar o CatPhotoApp novamente para praticar o uso de seletores CSS.

Para este desafio, você usará o seletor de atributo [attr=value] para estilizar as caixas de seleção (checkboxes) no CatPhotoApp. Este seletor busca e estiliza elementos que possuam um atributo e valor específico. Por exemplo, o código abaixo altera as margens de todos os elementos com o atributo type que possua o valor radio:

[type='radio'] {
  margin: 20px 0px 20px 0px;
}

--instructions--

Selecione todo elemento que possua o atributo type e tente dar às caixas de seleção no CatPhotoApp uma margem superior de 10px e uma margem inferior de 15px.

--hints--

Você deve selecionar as caixas de seleção (checkboxes) usando o seletor de atributo do tipo type.

assert(
  code.match(
    /<style>[\s\S]*?\[\s*?type\s*?=\s*?("|')checkbox\1\s*?\]\s*?{[\s\S]*?}[\s\S]*?<\/style>/gi
  )
);

As margens superiores das caixas de seleção devem ter 10px.

assert(
  (function () {
    var count = 0;
    $("[type='checkbox']").each(function () {
      if ($(this).css('marginTop') === '10px') {
        count++;
      }
    });
    return count === 3;
  })()
);

As margens inferiores das caixas de seleção devem ter 15px.

assert(
  (function () {
    var count = 0;
    $("[type='checkbox']").each(function () {
      if ($(this).css('marginBottom') === '15px') {
        count++;
      }
    });
    return count === 3;
  })()
);
