to use. It runs on Mac OS X, Windows and Linux and incorporates Cascading Style Sheets support and other improvements from software company Disruptive Innovations. Nvu was the brainchild of Kevin Carmony, CEO for Linspire, who wanted an easy-to-use, WYSIWYG HTML editor for Linux users. Under Carmony's direction, Linspire started and sponsored Nvu, hiring Daniel Glazman, former Netscape Communications Corporation employee, to be the lead developer.

Development

The original plan in June 2005 was to merge back the numerous changes into Mozilla Composer's source code tree. Since then the Mozilla Suite has been discontinued (then reintroduced as SeaMonkey), and no one has merged the Nvu code back into Composer.

Standards compliance

Nvu complies with the W3C's web standards. By default, pages are created in accordance to HTML 4.01 Transitional and use CSS for styling, but the user can change the settings and choose between: * Strict and transitional DTD's * HTML 4.01 and XHTML 1.0 * CSS styling or the old <font> based styling. The application includes a built-in HTML validator, which uploads pages to the

Shift to KompoZer

Daniel Glazman, the lead developer of Nvu, announced on September 15, 2006, that he had stopped official development on Nvu and that he was developing a successor as a Mozilla.org project. It is written from scratch and based on Mozilla trunk Gecko 1.9 and XULRunner. PHP and

would be supported. A community-driven fork, KompoZer, maintains Nvu codebase and fixes bugs until a successor to Nvu is released. Glazman's project is called BlueGriffon.
