HTML Tidy is a console application for correcting invalid HyperText Markup Language (HTML), detecting potential web accessibility errors, and for improving the layout and indent style of the resulting markup. It is also a cross-platform library for computer applications that provides HTML Tidy's features.

History

[edit]

HTML Tidy was developed by Dave Raggett[2] of the World Wide Web Consortium (W3C). Later it was released as a SourceForge project in 2003 and managed by various maintainers.[3]

In 2012, the project was moved to GitHub,[4] and maintained by Michael Smith, also of W3C,[5] where HTML5 support was added.

In 2015, the HTML Tidy Advocacy Community Group (HTACG) was formed for management and development of HTML Tidy as a W3C Community Group.[6][7]

HTML Tidy source code is written in ANSI C for portability. Compiled binary files are available for a variety of platforms. It is available under the W3C Software Notice and License, a permissive BSD-style license. Up-to-date versions are available as source code cloned from its GitHub Git version control repository, or in binary packages for multiple operating systems from its GitHub Releases repository.

Features

[edit]

Examples of corrections to invalid or poorly constructed HTML:

  • Reorder mixed-up tags
  • Complete missing or mismatched end tags
  • Add missing syntax elements (some tags, quotes, etc.)
  • Report proprietary HTML extensions
  • Change layout of markup to a predefined style
  • Transform characters from some encodings into HTML entities
