Syntax
Description
The
declare attribute declares an object, but doesn’t
instantiate it, which may be useful for the purposes of deferring the
object’s download until it’s actually needed. In HTML, it’s not necessary
to include the attribute and value pairing—all we need is the attribute on
its own, as shown here:
<object data="giant-dog.jpg" declare
type="image/jpeg" height="225"></object>
Example
Here’s the
declare attribute, specified in XHTML-compliant
markup:
<object data="giant-dog.jpg" declare="declare"
type="image/jpeg" height="225"></object>
Value
"declare" is the
only value this attribute can take.
