HTML and CSS Reference
In-Depth Information
It is not possible to document all the possible attributes that the many
different plug-ins might need with their associated
<embed>
tags. In-
stead, you must turn to the plug-in developer to learn about all of their
required and optional attributes for each plug-in that you plan to use in
your pages.
12.2.4.1.
The
align,
border,
height,
hspace,
vspace,
and
width
attributes
The browser displays embedded objects to the user in a region set aside
within the document window. The
<embed>
tag's
align
,
border
,
height
,
width
,
hspace
, and
vspace
attributes let you control the appearance of
that region exactly as they do for the
<img>
tag, so we won't belabor
them. [
<img>, 5.2.6
]
Briefly, the
height
and
width
attributes control the size of the viewing
region. Normally, you should specify the height and width in pixels, but
you may use some other units of measure if you also specify the
units
attribute (see
section 12.2.4.8
, later in this chapter). The
hspace
and
vspace
attributes define a margin, in pixels, around the viewing region.
The
align
attribute determines how the browser aligns the region within
surrounding text, and the
border
attribute determines the width of the
border, if any, surrounding the viewing region.
All the popular browsers support the
height
,
width
, and
align
attributes,
but unlike
<applet>
or
<object>
, Internet Explorer does not support
bor-
der
,
hspace
, or
vspace
for the
<embed>
tag.
12.2.4.2. The hidden attribute
The
hidden
attribute makes an object invisible to the user, forcing it to
have a height and width of 0. Note that setting
hidden
does not cause
the browser to display an empty region within the document, but rather
completely removes the object from the containing text flow.
