This attribute controls the scrolling of each frame. In this case, the left frame has scrolling disabled, while the right frame allows scrolling. This attribute assigns a name to each Frame. In this example, the frames are named left and right . This attribute controls the margins of each frame.
Higher numbers increase the size of the margins.
If it is omitted, the user may change frame sizes. Once the Frameset Document has been built, and includes links to all of the documents that will make up the individual frames, any other documents may be used as Body Documents, including other Frameset Documents. You can control which frame is used to display new material by including a target attribute in any link code in any frame. With this tag, you can specify that a user clicking on a link in one frame will see the linked document displayed within another frame. For example, if you are looking at this document in its framed version, clicking on either of the links appearing in the bottom window will cause the document appearing in the top window to change.
