The <frame> tag is placed inside the <frameset> container tags, and defines the individual attributes of a given frame. The 'src' attribute specifies the HTML document to be displayed in the frame. The 'name' attribute is used to identify frame's document, and, like the remaining attributes, is not mandatory. The 'noresize' attribute can be included to prevent the user from resizing the frame.

The 'scrolling' attribute affects the placement of scroll bars in the frame: a value of 'yes' will force scroll bars to appear; a value of 'no' will prevent scroll bars from being displayed, even when the document's length exceeds the frame space; and finally, 'auto' allows the browser to place scroll bars only where they are needed. The final two attributes -- 'marginwidth' and 'marginheight' -- specify the amount of space, in pixels, to place between the edge of the document and its contents.
