Different open source tools for developing Web applications

KompoZer

This is an open source HTML editor, which is based on the Nvu editor. It’s maintained as a community-driven software development project, and is a project on Sourceforge. KompoZer’s WYSIWYG (what you see is what you get) editing capabilities are among its main attractions. The latest of its pre-release versions is KompoZer 0.8 beta 3. Its stable version was KompoZer 0.7.10, released in August 2007. It complies with the Web standards of W3C. By default, the

Web pages are created in accordance with HTML 4.01 Strict. It uses Cascading Style Sheets (CSS) for styling purposes, but the user can even change the settings and choose between the following styling options:

HTML 4.01 and XHTML 1.0

Strict and transitional DTD

CSS styling and the old <font> based styling.

KompoZer can actually call on the W3C HTML validator, which uploads different Web pages to the W3C Markup Validation Service and then checks for compliance.
