WYSIWYG Editors for the Web
Not everyone who write content for the web know how to use HTML tags. Even if they do know, entering HTML tags to beautify their website content becomes a chore as they are distracted from the topic at hand. Fortunately, there are a number of online WYSIWYG editors which make formatting web pages a breeze.
The following are a couple of open source ones which have gained popularity on the web. All these WYSIWYG editors can be easily embedded in any website and they provide varying degrees of ease in HTML formatting and inserting images on your web pages.
WMD is a simple, lightweight HTML editor for blog comments, forum posts, and basic content management. You can add WMD to any textarea with one line of code. Add live preview with one line more. WMD works in nearly all modern browsers, and is completely free to use. It is more of a WYSIWYM editor and not a WYSIWYG one because it uses Markdown – a simple markup language – as an input format, converting ordinary text to structurally valid XHTML (or HTML) behind the scenes.
