HTML's textarea tag can produce great results, but is is one of the HTML tags that I don't see used very often.
The tag looks like this:
The results will look something like this:
<textarea rows="20" cols="60">
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, -- That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
textarea is good for displaying long text blocks, such as Terms or Service or Acceptable Use Policies, it is also great for displaying source code.
