There are two special tags for marking quoted text so that you can identify its author, origin, and language. Block-level quotes are generally indented by browsers. Inline quotes are supposed to be automatically enclosed in quotation marks but are not widely supported.
To quote block-level text:

To quote inline text:
Figure 4.12. Block quotes are generally indented from both sides. The cite attribute is not yet recognized by any browser I've seen.
