Hypertext Builder 2003 is an XHTML editor that combines visual capabilities with powerful coding tools.

Visual tools are provided for creating lists, tables, frames, formatted paragraphs, and image maps.

High-end coding features include popup references for tags, attributes, ASP, PHP4, and database schemas; automatic insertion of end tags, XHTML color-coding, and automatic backslashing of empty elements.

Hypertext Builder's XHTML language references are imported directly from document type definitions provided by the W3C.

Other XML languages Hypertext Builder 2003 supports include Open eBook, SMIL 1.0, SVG 1.0, WML 1.3, X3D, and XML Schema 1.0.

Database schemas can be imported from SQL Server, Access, MySQL, and Oracle via ODBC connections.

Built-in utilities include a thumbnail browser, a color-picker, multi-resolution preview, and a font browser.
