object is used to embed objects as part of HTML pages.

param elements should precede other content. Parameters

can also be expressed as attribute/value pairs on the

object element itself when brevity is desired.

abbreviated syntax where the param elements are replaced

table. The default units are screen pixels.
823
The frame attribute specifies which parts of the frame around
