## Preformatted Text

Typographically, preformatted text is not the same thing as code. Sometimes, a faithful execution of the text requires preformatted text that may not have anything to do with code. Most browsers use Courier and that’s a good default — with one slight adjustment, Courier 10 Pitch over regular Courier for Linux users.

### Code

Code can be presented inline, like <code>&lt;?php bloginfo('stylesheet_url'); ?&gt;</code>, or within a <code>&lt;pre&gt;</code> block. Because we have more specific typographic needs for code, we’ll specify Consolas and Monaco ahead of the browser-defined monospace font.

    #container {
	    float: left;
	    margin: 0 -240px 0 0;
	    width: 100%;
    }

## Blockquotes

Let’s keep it simple. Italics are good to help set it off from the body text. Be sure to style the citation.

> Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley, and he taught me to sing a song. If you’d like to hear it I can sing it for you. <cite>— [HAL 9000](http://en.wikipedia.org/wiki/HAL_9000)</cite>

And here’s a bit of trailing text.

## Embeds

Sometimes all you want to do is embed a little love from another location and set your post alive.
