CSE HTML Validator is a desktop application for Microsoft Windows XP, Windows Server 2003, Windows Vista, Windows 7, and Windows 8/8.1. It is developed and sold electronically by AI Internet Solutions LLC located in the Dallas–Fort Worth metroplex.[1] The first version of CSE HTML Validator was released in 1997 for Windows 95. The current version is 14.03[2] (as of May 15, 2014).

CSE HTML Validator is designed to help web developers create syntactically correct and accessible HTML, XHTML, and CSS documents (including HTML5 and CSS3) by locating errors and potential problems. Documents that have been checked with tools like CSE HTML Validator are more likely to be of better quality and be rendered as intended in a variety of mobile browsers and web browsers. CSE HTML Validator analyzes documents and suggests improvements, alerts developers to deprecated or proprietary tags, attributes, and CSS properties, and finds issues that can affect search engine rankings.

CSE HTML Validator includes an HTML editor, HTML validator, XHTML validator, CSS validator (with support for CSS3), PHP syntax checker, JavaScript checker (using JSLint), link checker (to find dead 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. Also included is a Batch Wizard tool that can check entire websites and multiple HTML/web documents.

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.

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.

There are four editions of CSE HTML Validator: Enterprise, Professional, Standard, and Lite.

CSE HTML Validator Pro is available as Demoware: It can be evaluated for a 30-day or 200 validation trial period. After expiration of this period, a regular license key must be purchased. The free lite edition does not require the purchase of a license.

Purpose of validation[edit]

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:

  • render faster and with fewer problems (user agents don't have to "figure out" and decipher bad syntax)
  • cause browsers and user agents to build a more consistent Document Object Model, which is important for CSS and JavaScript
  • be forward-compatible with future versions of user agents and browsers ("future-proof")
  • be compatible with current and future HTML, XHTML, and CSS specifications
  • render as intended on a variety of user agents, including mobile devices
  • cause fewer problems for visitors
  • be more accessible for people with disabilities (such as blindness), as well as users in general
  • not contain dead links

Differences from other HTML validators[edit]

  • CSE HTML Validator is an offline desktop app for Microsoft Windows (an online edition is available at OnlineWebCheck.com). The offline nature of the app is in contrast to online services like the W3C Markup Validation Service.
  • Checks HTML/XHTML syntax, CSS, links, spelling, accessibility, JavaScript, SEO, and PHP with one pass, while DTD-based validators are often more limited, checking mostly for basic tag structure and allowable attributes.
  • Provides better privacy and speed by checking documents locally. This is in contrast to HTML validators that require documents to be sent over the Internet to be checked remotely, and then the results sent back.
  • Includes a DTD-based validator which can optionally be used for checking DTD-based versions of HTML (versions prior to HTML5), however one of CSE HTML Validator's primary differences is that its custom validation engine can perform more checks on a document than a DTD-based validator can. This is because DTD-based validators are limited to checking only what can be specified in a Document Type Definition.

Automatic document fixing[edit]

Using a version of HTML Tidy with HTML5 support and the Format and Fix Tool, CSE HTML Validator can automatically fix certain problems with HTML and XHTML documents. However, some problems cannot be fixed (or fixed correctly) with automated tools and require manual review and repair.

Limitations[edit]

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.

The desktop edition of CSE HTML Validator is currently only available for Windows, although it can still be used on a Mac if it is set up to run Windows applications (like with Parallels Desktop for Mac).

Integration with other software[edit]

CSE HTML Validator integrates with other 3rd party software like those listed below. This allows validation using CSE HTML Validator from within the 3rd party program.

Online version[edit]

An online edition is available at OnlineWebCheck.com. The online edition is based on CSE HTML Validator Pro and can check documents via file upload, URL, or snippets (direct text input).
