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
HTML Tidy was developed by Dave Raggett{{cite web | url=https://www.w3.org/People/Raggett/tidy/ | title=Clean up your Web pages with HTML TIDY | first=Dave | last=Raggett | work=W3C.org | access-date=2015-02-12}} (Dave Raggett's legacy HTML Tidy page.) of the World Wide Web Consortium (W3C). Later it was released as a SourceForge project in 2003 and managed by various maintainers.{{cite web|url=http://tidy.cvs.sourceforge.net/tidy/ |title=SourceForge.net Repository - [tidy] Index of / |publisher=Tidy.cvs.sourceforge.net |access-date=2015-04-25}}
In 2012, the project was moved to GitHub,{{github|w3c/tidy-html5}} and maintained by Michael Smith, also of W3C,{{cite web | url=https://people.w3.org/mike//| title=Michael[tm] Smith | first=Michael | last=Smith | work=W3C.org | access-date=2015-02-12}} 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.{{cite web|url=http://www.htacg.org |title=HTACG |publisher=HTACG.org |access-date=2015-04-25}}{{cite web|author=Jim Derry |url=https://www.w3.org/community/htacg/ |title=HTML Tidy Advocacy Community Group |date=15 January 2015 |publisher=W3.org |access-date=2015-04-25}}
