WYSIWYG (What You See Is What You Get) editors are HTML editors that attempt to display the Web page as it will show on the browser. They are visual editors, and you don't maniulate the code directly. Some HTML WYSIWYG editors also include a text editor, while others are purely WYSIWYG. This is my list of the best HTML WYSIWYG editors for Macintosh.
EditLive! is a standard WYSIWYG HTML editor. It offers the ability to edit both in WYSIWYG mode and in HTML mode. One of the things I liked was that it has a built-in accessibility analyzer. This makes it easy to write accessible pages. But if it had an HTML validator I couldn't find one.

Image courtesy AdobeContribute is a WYSIWYG editor that is intended to work in tandem with Dreamweaver. While it is possible to create and maintain a Web site with Contribute, there are some features noticeably missing, like spell check and forms. It is a good editor for clients who want some control over the content of their pages, but don't want to handle the design and programming aspects.
Web Studio 4.0 is trying to answer the challenge of Web design tools that tools like Word have provided. Namely, the idea that you should be able to build a Web page by simply dragging the images or multimedia elements that you want onto your document and then typing text around them. Web Studio 4.0 does a good job at this - by making the creation of a Web page easy to understand, by removing all direct access to it from the user.
eWebEditPro is an online, browser-based Web editor for businesses. The idea behind this editor is that it offers WYSIWYG editing capability wherever you are. You just pull up a browser, go to the page that needs editing and login to the editor to edit it.
EditLive! for XML is an XML editors for companies that need to allow XML manipulation by non-technical developers. It is one of the few WYSIWYG XML editors I've seen. The editor takes the schema or DTD and turns it into a form for the user to fill in the data. It wouldn't work well as a Web page editor, but if you have customers who need to use XML but aren't comfortable with it, this would be a great solution.
Netscape Composer is a simple little Web page editor that comes included with Netscape. There isn't a lot to recommend it other than that it's free and is built-in to your Web browser. Feature highlights: WYSIWYG XHTML editing.
Radio is a software package that connects you to the Radio UserLand Web log service. It's not really a standalone Web page editor, but if all you need or want is a Web log, then this service is nice. It includes 40MB of space and a year of service on the Radio UserLand network.
Freeway Express is a great basic Web page editor for the Macintosh. It includes basic graphics editing and creation so that you only need one software package to create simple Web sites. One drawback is that you can only save your files as HTML 4, there is no support for any other DTD.
Create is an extensive graphics manipulation program that also acts as a Web page editor. It provides WYSIWYG functionality to make it easy to place objects and elements. But it's true strength is in the graphics manipulation features it has. You can create text and image objects and then manipulate them in many ways. It is quite fun to use.
eWebEditPro+XML offers the same benefits as eWebEditPro only it's for XML editing rather than HTML or Web pages specifically. This is a browser-based XML editor that edits the XML files on the server.
