For most professional developers, there is no better web design software than Dreamweaver.  But Dreamweaver is expensive, and most people getting started in web development won’t want to spend $399 US on web design software.  I think the best choice for someone looking for inexpensive web design software is the Coffee Cup HTML Editor.  For $49.00 US, the Coffee Cup HTML Editor is packed with features, and it should be relatively easy for use by beginners.  It has both a visual (WYSIWYG) editor, an (X)HTML code editor, and a CSS editor.  It includes many features found in Dreamweaver, such as project/site management and a find and replace tool that provides options to make changes to a single file, all open files, or all files in a specified folder.  To help users get started, the program comes with ten themes, and additional themes are relatively inexpensive.  All the themes I looked at use CSS layouts and valid (X)HTML code.  For more information, visit the Coffee Cup HTML Editor website.
