When editing HTML it's easy to make mistakes. Wouldn't it be nice ifthere was a simple way to fix these mistakes automatically and tidy upsloppy editing into nicely layed out markup? Well now there is! DaveRaggett's HTML TIDY is a free utility for doing just that. It also worksgreat on the atrociously hard to read markup generated by specializedHTML editors and conversion tools, and can help you identify where youneed to pay further attention on making your pages more accessible topeople with disabilities.
Tidy is able to fix up a wide range of problems and to bring to yourattention things that you need to work on yourself. Each item found islisted with the line number and column so that you can see where theproblem lies in your markup. Tidy won't generate a cleaned up versionwhen there are problems that it can't be sure of how to handle. Theseare logged as "errors" rather than "warnings".
