CSE HTML Validator is a native desktop software application for Microsoft Windows. The software assists web developers in creating syntactically correct and accessible HTML, XHTML, and CSS documents (including HTML5 and CSS3) by locating errors, potential problems, and common mistakes. It is also able to check links, suggest improvements, alert developers to deprecated, obsolete, or proprietary tags, attributes, and CSS properties, and find issues that can affect search engine optimization.

CSE HTML Validator is developed, marketed, and sold by AI Internet Solutions LLC located in Texas. The first version of CSE HTML Validator was released in 1997 for Windows 95. The current version is 17.01 (as of January 25, 2017). There are four major editions of CSE HTML Validator — Enterprise, Professional, Standard, and Lite. While the application is generally a commercial product (except for the lite edition), a free version of the standard edition is available for personal, non-commercial use.
Features
CSE HTML Validator includes an HTML editor, HTML validator, XHTML validator, CSS validator (with support for CSS3), PHP syntax checker, JavaScript checker (using JSLint and/or JSHint), link checker (to find dead and broken links), spell checker, accessibility checker, search engine optimization (SEO) checker, integrated HTML editor, and integrated web browser. The integrated web browser allows developers to browse the web while the pages are automatically validated.
Because documents are checked locally and not uploaded over the Internet to a server in order to be checked, validations are performed relatively quickly, and security and privacy are increased.
A Batch Wizard tool, included in some editions of the software, can check entire Web sites, parts of Web sites, or a list of local web documents. The Batch Wizard generates reports in HTML or XML format. The reports can be viewed using a standard web browser.
Validation of polyglot markup was added in CSE HTML Validator v12, and mobile development support (for HTML & CSS) was added in CSE HTML Validator v14 and improved in v15. Version 15 added built-in syntax checking for JSON and HTML5 cache manifest files. Version 16 added JavaScript linting using JSHint, a static code analysis tool for checking JavaScript, but also continues to support JSLint. Version 17 added support for the Accelerated Mobile Pages Project, which is a type of HTML optimized for mobile web browsing, and support for live DOM validation using Firefox and an add-on.
The accessibility checker includes support for Section 508 Amendment to the Rehabilitation Act of 1973 and Web Content Accessibility Guidelines (both WCAG 1.0 and WCAG 2.0). Current versions also provide support for Canada's Common Look and Feel (CLF), including CLF 2.0.
Using a version of HTML Tidy with HTML5 support and the Format and Fix Tool, CSE HTML Validator can automatically fix some common problems with HTML and XHTML documents. However, some problems cannot be fixed (or fixed correctly) with automated tools and require manual review and repair.
An online edition based on CSE HTML Validator Pro can check documents via file upload, URL, or snippets (direct text input). It supports HTTPS for security and privacy. The desktop edition of CSE HTML Validator is currently only available for Microsoft Windows.
Purpose of validation
The purpose of validation and computerized checking of HTML, XHTML, and CSS documents is to help make sure that the documents are syntactically correct and problem-free. Checked HTML, XHTML, and CSS documents are more likely to:
While automated checking tools are helpful for website development and maintenance, they cannot guarantee that a document will display as intended in all browsers. Developers should always test documents in a variety of browsers (including mobile browsers) to locate problems that cannot be detected with a computerized checking tool.
