Blockquote

A blockquote separates "what someone else said" from the author's own writing: a famous quote, a line from a user interview, a passage from another article, or the original message kept in an email reply. In HTML, it's the blockquote tag. The common style is a 3 to 4px vertical bar on the left, the whole passage indented, text a little lighter or in italics, and a line below like "— Liam Carter, CTO at Acme" naming the source (inside cite or figcaption). Magazine-style pages also use a "pull quote": one sentence from the body, enlarged and centered with big quotation marks, as a visual highlight.

It's easy to confuse with an Alert, because docs sites often draw "Note" and "Tip" boxes with a bar on the left too. An alert is the author's own reminder, with an icon and colors that show how serious it is. A blockquote is someone else's words and doesn't mean any status. How it differs from a Testimonial: testimonials are cards on a marketing site with an avatar, name, company, and star rating, meant to show the product is good. A blockquote is just a quoted passage in the body text.

Only use blockquote when you're actually quoting someone, not to make a paragraph look nicely indented. Say clearly who said it and where. If the original is long, pick the key sentence. Leave paragraph spacing above and below, and keep the bar light gray or a pale brand color so it doesn't outshine the text.
