HTML-TEMPLATE is a portable library for Common Lisp that can be used to fill templates with arbitrary (string) values at runtime. It is intended to be used for HTML and is loosely modeled after the HTML::Template Perl module. It translates templates into efficient closures that can be re-used as often as needed, and uses an intelligent cache mechanism that allows templates to be updated while your program is running.
EZ Reusable Objects (EZRO) is a Web application that can be used by non-technical staff to manage content as "objects." Content objects containing text, video, and audio can be shared, modified, and re-styled to appear via a traditional Web site, an on-line course, an innovative "Coach," or as a community of interest site. It is highly scalable and can be used for public Web sites, secure environments, and private intra/extranets.
DHTML API allows you to animate your Web site with the aid of DHTML. Any content that you place within a div tag with the position CSS attribute set to absolute can be manipulated like a sprite. Just don't forget to set id="unique_name", and pass "unique_name" to the GetLayer() function.
