About CSS HTML Validator for Windows, Mac, and Linux is a fast, powerful, highly user configurable, and easy to use web development tool that checks HTML, CSS, SEO, spelling, accessibility (including WCAG 2.0/2.1/2.2), PHP, XHTML, JavaScript, htmx, and links. CSS HTML Validator includes batch processing (in the Pro edition), integrated HTML/CSS editing, and much more. It works offline so it's super-fast and your privacy is protected because your documents are not uploaded to a server for checking. CSS HTML Validator Pro has superior customization features so you can configure the validation to your liking. You can even add your own validator messages, recognize your own HTML elements and attributes, and much more. Try CSS HTML Validator Pro for Windows free for 200 validations or 30 days, whichever comes first. A FREE limited version of htmlval for Mac and Linux is also available.	About mPDF is a PHP library that generates PDF files from UTF-8 encoded HTML. It is based on FPDF and HTML2FPDF with a number of enhancements. It is slower than the original scripts e.g. HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles, etc., and has been much enhanced. mPDF as a whole is quite a dated software. Nowadays, better alternatives are available, albeit not written in PHP. Use mPDF if you cannot use a non-PHP approach to generate PDF files or if you want to leverage some of the benefits of mPDF over the browser approach, color handling, pre-print, barcodes support, headers and footers, page numbering, TOCs, etc. But beware that an HTML/CSS template tailored for mPDF might be necessary. If you are looking for state-of-the-art CSS support, mirroring existing HTML pages to PDF, use headless Chrome. mPDF will still be updated to enhance some internal capabilities and to support newer versions of PHP.

Pros & Cons from Real Users Pros What is just as important as high quality of a tool? A developer’s willingness to keep driving their project forward in an evolutionary way! Albert Wiersch is just such a developer. You can sense his passionate attention to detail throughout the programme, in the configuration, in the documentation and in the output. Thank you, Albert, for this brilliant work! I starting using this five years ago, and have not looked back since. It really is a one-stop shop for keeping your code free of any problems. By finding issues in your code, however minor they might seem, you can keep your code clean, and this leads to far fewer problems in the long run. Without it, minor issues aren't caught, but at some stage they accumulate and then you end up with a big mess which is much harder to sort out. Good support if you have any problems in implementation. Highly recommended. Excellent syntax checking that, in addition to locating errors, offers relevant targeted advice on correcting errors, best practices, accessibility, and SEO, making CSS HTML Validator a good tool when learning HTML, CSS, etc., and a sophisticated advisor even for an advanced practitioner. In addition to validating single HTML/CSS pages, it checks links and is able to process an entire website to generate a comprehensive analysis of all pages. The website can be local on the file system or online and accessed via a URL. The validator engine allows one to choose the level of error checking (Full, Errors only, Errors and warnings only, etc.) and enabling/disabling specific messages. The editor includes features specific to editing HTML and CSS pages. Validation includes JSON (in HTML pages) and WCAG (Web Content Accessibility Guidelines). The ASPX pages are html nightmares for the most part. By testing the runtime manifestations against this product (in other words, grab the page source and drop it into this product), I can see a number of things that need to be addressed in the source - css, poor document structure The only limitation I have run into is that I need to embed css links in the pages explicitly instead of relying on the Telerik style sheet manager to organize and provide them to the app. It would be very helpful if a set of CSS stylesheets could be automatically searched and so on. Love the way it tells you the line and the error message. Makes troubleshooting very easy. Just open your file and click validate, just that easy. Cons I found nothing of relevance. May be I overlook something. Nothing. If I had any difficulty in implementing a particular option, I contacted support and the problem was sorted. As with any product, various individuals will have various preferences, but, for myself, I am at a loss to suggest possible improvements. As one who runs Linux, the fact that CSS HTML Validator is a Windows-only application was a "con" (I ran it in a VM), but, as of Wine 9.0, all features of CSS HTML Validator perform flawlessly when installed on Linux with Wine. I am not sure why I get the starting panel offering me options on startup. Maybe it can be disabled. A bit annoying. Wish there was a lifetime price for upgrades, but am satisfied with the current pricing per version.
