Adobe Dreamweaver is a web development tool for creating, publishing, and managing websites and mobile content. It allows users to design visually or directly in code, develop pages with content management systems, and accurately test browser compatibility. It provides a visual WYSIWYG editor and a code editor with standard features such as syntax highlighting, code completion, and code collapsing, as well as more sophisticated features such as real-time syntax checking and code introspection for generating code hints to assist the user in writing code.
