A pre element is a block level element that can be used directly as a sub-element in the body element. You can use pre elements to specify blocks of pre-formatted text with white space characters preserved. Here are basic rules about pre elements:

"pre" elements are mixed content elements.
"pre" elements can have empty contents.
"pre" elements can have PCDATA as contents.
"pre" elements can have in-line elements as contents.
"pre" elements can not have block elements as contents.
"pre" elements are block elements. They can not be used as in-line elements.
"pre" elements will be displayed by browsers without line wrapping. So long lines in the document will be displayed as long lines.
"pre" elements will be displayed in monospacing fonts in browsers by default.
"pre" elements preserve white space characters.

Here is a good example of pre elements:

<body>
<pre>
     1
    1 1
   1 2 1
  1 3 3 1
 1 4 6 4 1
</pre>
