(1) On web pages, a scrolling area of text. Starting with Version 2, Microsoft Internet Explorer supports a special tag for creating these areas. Netscape Navigator, however, does not support this tag. You can also create marquees with Java applets and Dynamic HTML.
(2) In graphics software, a sizable and movable frame that identifies a selected portion of a bit-mapped image. The marquee frame can be rectangular in shape or, in some cases, irregular. A lassotool, for example, enables you to select all contiguous portions of an image that share the same color.
The marquee frame is usually displayed with a flashing dashed line. In fact, that explains the origin of the name, since the dashed lines look a little like the flashing lights around a theater entrance, which is also called a marquee.
