{{pre}} uses <pre> tags, but with text that is either wrapped or is contained in a horizontal scrollbox. This means the text will not stretch past the right side of the screen.

As it uses real <pre> tags , it will be displayed correctly regardless of how the user's skin renders <pre> boxes.

If you want to disable wikitext in it, you should use <nowiki> tags inside the template (see below).

{{pre|Text to be displayed. And more and more and more... and a paragraph break.

And then more and more...}}

produces:
Text to be displayed. And more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and a paragraph break.

And then more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more.

{{pre|scroll|Text to be displayed. And more and more and more... and a paragraph break.

And then more and more...}}

produces:
Text to be displayed. And more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and a paragraph break.

And then more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more.

To disable wikitext (e.g. [[links]]), <nowiki> tags must be used in the form:

{{pre|<nowiki>Your [[text]], which ''might'' include {{tl|templates}}.<noinclude>[[Category:Examples]]</noinclude></nowiki>}}

This will produce this:

Your [[text]], which ''might'' include {{tl|templates}}.<noinclude>[[Category:Examples]]</noinclude>

as opposed to:

Your text, which might include {{templates}}.
