Code Mirror
The CodeMirror editor is designed to make it easy to enter HTML code in an article or description. CodeMirror supports syntax highlighting and auto-completion, as shown in this screenshot.
CodeMirror offers some of the same advantages of using No Editor, but makes it somewhat easier to work with raw HTML code.
