Qual é Lorem Ipsum?
 
Lorem Ipsum é simplesmente texto manequim da impressão e composição 
indústria. Lorem Ipsum tem sido o texto padrão do manequim da indústria 
desde os anos 1500, quando uma impressora desconhecida tomou uma galera
de tipo e mexidos-lo para fazer um livro tipo espécime. Ele sobreviveu
não apenas cinco séculos, mas também o salto para composição eletrônica, 
permanecendo essencialmente inalterado. Foi popularizado na década de 1960
com o lançamento de folhas Letraset contendo Lorem Ipsum passagens, e mais
recentemente com software de editoração como Aldus PageMaker, incluindo 
versões de Lorem Ipsum.

What is Lorem Ipsum?
 
Lorem Ipsum is simply dummy text of the printing and typesetting industry. 
Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, 
when an unknown printer took a galley of type and scrambled it to make a type 
specimen book. It has survived not only five centuries, but also the leap 
into electronic typesetting, remaining essentially unchanged. It was popularised in 
the 1960s with the release of Letraset sheets containing Lorem Ipsum passages,
and more recently with desktop publishing software like Aldus PageMaker including 
versions of Lorem Ipsum.
