TSynHTMLSyn is a component that provides the HTML syntaxchecking-part of syntax-highlighting editing. It is part of the SynEdit package and is available under the SynEdit tab of the Component Palette.
TSynHTMLSyn is used in conjunction with a display component like TSynEdit that is connected through the Highlighter property of the TSynEdit.
