Template:Blockquote/doc/boilerplate

The Manual of Style guidelines for block quotations recommend formatting block quotations using the {{Blockquote}} template or the HTML <blockquote> element, for which that template provides a wrapper.

Quotes work best when used with short sentences, and at the start or end of a section, as a hint of or to help emphasize the section's content.
For typical quotes, especially those longer than the rest of the paragraph in which they are quoted, {{Cquote}} (for use outside of article space only) provides a borderless quote with decorative quotation marks, and {{Quote frame}} provides a bordered quote. Both span the page width.
For very short quotes, {{Rquote}} (with decorative quotation marks, for use outside of article space only) or {{Quote box}} (framed) can be used to set the quote off to either the right or left as in a magazine sidebar. This can be effective on essay pages and WikiProject homepages.
