About "pre" and "code" style

I very like the <pre> and </pre> style of the Sun Microsystems.

This is the test code.

single line style code
style=" color: black; font-family: Courier, monospace; background-color: #efefef; border: 1px solid #ccc; font-size: 100.01%; padding: 0.5em; overflow: hidden;"

CSS code
code, pre {
    color: black;
    font-family: Courier, monospace; /* [3] */
}
pre {
    background-color: #efefef;
    border: 1px solid #ccc;
    font-size: 100.01%;
    padding: 0.5em;
    overflow: hidden;
}
