you should use the <blockquote> element for it's intended semantic purpose.

http://www.w3.org/TR/html-markup/blockquote.html [w3.org]:

The blockquote element represents a section that is quoted from another source.

for what you are describing i would use a <p> element if it's a paragraph or a <div> element if you need a more generic container.

and i would definitely use external styles as described by rainborik.
