BlueGriffon takes a straightforward WYSIWYG (What You See Is What You Get) approach to web editing, but also manages to include plenty of more powerful features. It is based on the rendering engine of Mozilla Firefox.
You could just use it to type text, insert images, tables, audio files, videos and so on. But there’s also an SVG editor, form design tools, some CSS support, an accessibility checker, DOM Explorer, and more.
BlueGriffon is free but does utilize commercial plugins, so you may find that some features link you to a web store to purchase these plugins.
