I started with the free version in the late 1990s and upgraded to the Pro version later on when I taught Web design regularly. I continue to recommend it to my students when I find out they are doing any kind of webpage development. I use it to batch validate student websites. I share the generated reports with their grading rubric so they not only know what they did wrong, but how to fix it.
Pros
Easy for novice users. Highly customizable for expert users. Editor and validators are customizable. Excellent technical support. Validates within the editor. Has a batch mode that generates validation information, explanations, and ways to fix code that can be shared with other developers. Intuitive interface. Stays current with published standards. Can clean up code.
Cons
It would be nice to have a code completion feature similar to Visual Studio or Notepad++.

Based on more than two decades using CSS HTML Validator under Windows and, more recently, under Linux, I recommend it highly, not only to anyone learning web development, but also to experienced developers who pride themselves on clean, standard-compliant code, or whose code is subject to the accessibility requirements of WCAG and Section 508, or who need advanced capabilities for website monitoring. A test run of CSS HTML Validator is possible by taking advantage of the free trial offer.
Pros
In the mid-1990s, I found CSE HTML Validator’s tight integration of syntax checking with an HTML editor very effective, and its recommendations for fixes and best practices were very much like having a mentor. In the following years, CSE HTML Validator evolved into CSS HTML Validator, and its syntax checking and mentoring stayed up-to-date with evolving standards for web development. Throughout this period, I continued to rely on it because of the enormous convenience of its integration of syntax checking with editing HTML, CSS, JavaScript, and PHP. Some syntax checkers require code to be uploaded to an online service, but CSS HTML Validator’s syntax checking is purely local. That means code is kept private, and syntax checking is fast. While the Standard edition is targeted to working with individual web pages, the Professional and Enterprise editions include a batch processor for monitoring and maintaining entire websites. Using the batch processor, I am able to subject a website to an exhaustive analysis, including syntax checking, validation of links, and recommendations for best practices. It can also check WCAG and Section 508 accessibility requirements. CSS HTML Validator may be a Windows application, but I have found that it executes flawlessly on Linux machines using Wine, which enabled me to continue relying on it when I switched from Windows to Linux. A complete technical evaluation of CSS HTML Validator is available on the WineHQ Wine Application Database.
Cons
Because CSS HTML Validator lacks a builtin FTP client, it cannot directly upload web pages to a web site.

Pros
I think this software is great. The pro version is the best because it analyzing the entire website and not just individual pages. I’ve used google webmaster tools but I prefer CSS HTML Validator because it really fine tunes the code mistakes i typical mess up on. There’s no builtin FTP client, Which is a bummer but overall it still allows me to clean up errors and make my code on the sites load faster across windows and Linux.
Cons
Besides no FTP, I havnt had any cons about the software.

It's helped me write robust HTML and CSS, and it's helped me learn the reason why certain things should be structured in the way that allows validation.
Pros
The CSS HTML Validator provides a better analysis of HTML than what is provided by the W3C: the Validator provides clear and detailed information not only of the cause of what problems it discovers, but helpful suggestions on how to solve those problems. It then goes beyond that to provide suggestions on what might be done to strengthen the HTML beyond a mere validation fix, including information on accessibility, cross-browser compatibility, and the like. There's also the added bonus of an online forum where questions may be posted, and the author of the software has always been quick to respond to queries, and he has been equally open to suggestions of new features (e.g., when I've discovered quirks of HTML composition that result from the use of certain JavaScript frameworks, the author has worked to ensure that the Validator responds to those quirks with appropriate validations and suggestions for usage). I recommend the Validator highly to everyone who wants to ensure that their HTML and CSS are rock-solid, and therefore a strong foundation for their application and its use.
Cons
If I could choose the default sound that is issued at the end of validation (a triumphant "ta-da!" when everything checks out, a single low "beep" when there's a problem), I'd probably want that. But the program is so highly configurable that there's probably a setting for changing those sounds that I haven't investigated yet. :-)

Has helped immensely in Webpage design--especially before the era of content management systems. Remember, if someone doesn't like the looks of your site, he will switch off in three seconds. Also useful when doing bulk e-mails, using such programs as Atomic Mail Sender. This stuff has to look perfect to even have a chance of being read.
Pros
Does a complete validation of your web page, checking for essentially all possible errors. If you want the best look and functionality of your site's pages, the code has to be correct. Sure...browsers are more forgiving these days, but why take a chance? What's more, by having coding errors exposed, you learn how to design the pages better!
Cons
In some rare cases, the Validator can get too picky. e.g. For MailChimp e-mailing software, certain aspects of generated inline CSS coding are technically wrong, and will actually not render if corrected to the Validator's standards. Note that this is not a problem with the Validator, but with MailChimp. This sort of thing can also occur in WordPress. Thus, the user must be aware of those rare instances when being absolutely correct can be a problem.

I am very impressed with CSS HTML Validator software. It is a powerful editing tool for HTML, XML, CSS and other forms of web documents. The validator saves a lot of time reviewing code for syntax, nesting errors, and other coding mistakes. You can choose the level of error reporting from critical errors only, or add warnings, link checking, and even suggestions on good style practices and appropriate coding for web crawlers. When validating documents, errors are highlighted in different colors, indicating the severity of the mistake. And the validator allows you to choose to validate with the HTML 5 standard or select earlier, transitional versions. The Validator makes writing code quicker and easier than using a plain text editor. You can choose to have your tags auto-closed, and lines auto-indented to help avoid nesting errors. Spelling and syntax suggestions are available on-the-fly. The editing screen can be split horizontally or vertically between two documents allowing for quick and simple cut-and-paste, or side-by-side comparison of two documents, and the edit screen will hold multiple files open with quick-access tabs allowing you to switch rapidly between documents. Although the Validator is not a WYSIWYG editor, it quickly allows you to check the web display of your document using either an internal browser, or your choice of popular browsers through an external link. The Validator constantly follows your cursor, so help from their on-line syntax database is on
Pros
Even though this software is heavily packed with features, I appreciate the intuitive layout, the ease of use, and the low learning curve; I was up and running very quickly.
Cons
No What-you-see-is-what-you-get capability.

Pros
CSS HTML Validator makes sure that aqua-calc.com with its more than 800,000 pages runs free of any HTML issues since 2011, providing for quick and reliable way to check any web page in development. Its batch wizard allows to stay on top of any inadvertently introduced errors during a development phase. CSS HTML Validator is a significant part of aqua-calc.com nightly builds, ensuring that search engine bots will not not find any HTML issues within the website. Lastly, but not least, in my experience, CSS HTML Validator provides stellar support, responding promptly and efficiently to any and all questions.
Cons
It takes about 10 hours for CSS HTML validator batch wizard to scan aqua-calc.com, but sheer amount of pages within the website makes it unavoidable.
