The follow-up to Netscape Communicator, Netscape 6 (released in 2000), dropped support for JSSS. It now remains little more than a historical footnote, with web developers generally unaware of its previous existence. The proposal did not become a W3C standard.

Syntax
Using JavaScript code as a stylesheet, JSSS styles individual element by modifying properties of a document.tags object. For example, the CSS:
h1 { font-size: 20pt; }
is equivalent to the JSSS:
document.tags.H1.fontSize = "20pt";
JSSS element names are case sensitive.
JSSS lacks the various CSS selector features, supporting only simple tag name, class and id selectors. On the other hand, since it is written using a complete programming language, stylesheets can include highly complex dynamic calculations and conditional processing. (In practice, however, this can be achieved using JavaScript to modify the stylesheets applicable to the document at runtime.) Because of this JSSS was often used in the creation of dynamic web pages.
Example
The following example shows part of the source code of an HTML document:
