This diagram illustrates how content may overflow a box.
Two boxes are shown. The first one has a red border and is labeled DIV. The upper left corner of the second box, labeled BLOCKQUOTE, is positioned in the middle of the DIV box. The BLOCKQUOTE box has a black dashed border and contains the following text, attributed to Groucho Marx: "I didn't like the play, but then again I saw it under adverse conditions - the curtain was up." The BLOCKQUOTE box overflows the DIV box to the right and below it. Since the 'overflow' property on BLOCKQUOTE is 'visible', the overflowing text remains visible.
