Given the very fast moving nature of Web technology, Amaya has a central role to play. With such an interface, users do not need to know the HTML or CSS languages. Adobe GoLive is a complete web design tool and site management package. It won't change your HTML unless you ask it to. In a text-based editor, a web site is as accessible as you make it.
Some editors provide functionality which make it easier to produce or test for accessibility.
Here are a few. BBEdit is a basic text editor with powerful features and a full suite of HTML tools. The lite version is free, the pro version comes with more useful plugins, an HTML checker, link checker, HTML aware spell checker, and other useful features. As you type, HotDog provides continual feedback on the HTML code you are using. This feedback takes the form of tool tips which explain what each tag and attribute does.
