Why is it used?

It has long been found that when evaluating design and composition, the readable text interferes with concentration. Lorem Ipsum is used because it provides more or less standard template filling, as well as the actual distribution of letters and spaces in paragraphs, which does not work with simple duplication "Here is your text .. Here is your text .. Here is your text .." Many programs HTML and HTML editors use Lorem Ipsum as their default text, so a search for the keywords "lorem ipsum" immediately shows how many web pages are still waiting for their real birth. Over the years, the text of Lorem Ipsum has received many versions. Some versions appeared by mistake, some - intentionally (for example, humorous variants).
