CSS HTML Validator

CSS HTML Validator is both a powerful tool to check the correctness of the written code in HTML pages and an HTML code-writing editor. Creators of CSS HTML Validator claim that their offline version is much better than the online validators.

CSS HTML Validator contains a full-featured HTML and text editor and checks the HTML pages for error in code, typos in tags, and the Web site attributes. The program detects unnecessarily open or closed tags, attributes with small and large letters, quotation marks for the attributes, and performs a comprehensive syntactic check of the written HTML-code. CSS HTML Validator checks external and internal references. Allows batch mode to check files, which can be started with one click. License: Paid (Trial).
