Instruções

Por último, para o botão de envio, você quer separá-lo do fieldset acima e ajustar sua largura para nunca ficar abaixo de 300px. Altere a propriedade margin para que inclua 1em nas partes superior e inferior e, ao mesmo tempo, deixe as margens esquerda e direita definidas como auto. Em seguida, defina a largura conforme descrito acima.

O que fazer:

Testes:

Você não deve alterar a propriedade `width`. Use a propriedade `min-width`.
Você deve usar a propriedade existente `margin` para incluir `1em` nas partes superior e inferior.
