HTML <pre> tag
Definition and Usage
The pre element defines preformatted text. The text enclosed in the pre
element usually preserves spaces and line breaks. The text renders in a fixed-pitch
font.
Differences Between HTML and XHTML
The "width" attribute of the pre element was deprecated in HTML 4.01.
The "width" attribute of the pre element is not supported in XHTML 1.0 Strict DTD.
Note on <pre>
It is worth noting that while <xmp> is deprecated, the <pre>
tag does not perform all of the functions of <xmp>:
<pre><b>Hello</b></pre> displays Hello
<xmp><b>Hello</b></xmp> displays <b>Hello</b>
