Dynamic Styles and CSS
CSS defines how particular elements within the document are to be
rendered. The object model for manipulating the properties of the style sheet is
based on the CSS recommendation. When an attribute or rule is modified
through script, the static style sheet is updated and the page is immediately updated.
This dynamic style model is different from the JASS model supported
by Netscape Navigator 4.0. JASS is a procedural model for defining a style
sheet for the document at parse time rather than a programming model for
manipulating a document's style. For example, JASS can be used to write
conditional code that applies a different style sheet depending on the size of the
screen during the loading of the document. JASS can't be used to change the style
of an element in response to an event without reloading or requesting a new
page from the server.
In Microsoft Internet Explorer 4.0, dynamic styles are not a
procedural style sheet language, but they can accomplish all aspects of JASS and
much more. Rather than define an alternative style sheet language, dynamic
styles in Internet Explorer modify the document's CSS-defined style sheet by
allowing you to define inline style properties on every element, enable and disable
all global and linked style sheets, and add rules to and changes rules on an
existing style sheet. [Содержание]
