HTML and CSS Reference
In-Depth Information
src
This attribute specifies the URL of source content for the embedded object.
type
This attribute specifies the MIME type of the embedded object. It is used by the
browser to determine an appropriate plug-in for rendering the object. It can be used instead
of the
src
attribute for plug-ins that have no content or that fetch it dynamically.
units
This Netscape 4+-specific attribute is used to set the units for measurement for the
embedded object in pixels or as a relative em value.
vspace
This attribute specifies, in pixels, the size of the top and bottom margins between
the embedded object and surrounding text.
Example
<!-- embed with a close tag -->
<embed src="testmovie.mov" height="150" width="150">
<noembed>
<img src="testgif.gif" height="150" width="150" alt="Test Image">
</noembed>
</embed>
Compatibility

Notes
• Historically, it has been unclear whether or not the close tag for
<embed>
is required.
Many sites tended not to use it, and documentation is not consistent. A close
</embed>
tag should be required and should surround any alternative content in a
noembed
element.
• This element was supposed to be phased out in favor of the
object
element, but so
far its usage seems to have diminished only slightly.
• The
embed
element is not favored by the W3C and was dropped by (X)HTML
specifications previous to HTML5.
• Embedded objects are multimedia content files of arbitrary type that are rendered by
browser plug-ins. The
type
attribute uses a file's MIME type to determine an
appropriate browser plug-in. Any attributes not defined are treated as object-specific
parameters and are passed through to the embedded object. Consult the plug-in or
object documentation to determine these.
<fieldset> (Form Field Grouping)
This element allows form designers to group thematically related controls together. The
element usually contains a
legend
element, which labels the grouped form controls.
Standard Syntax
<fieldset
class="class name(s)"
dir="ltr | rtl"
