No! No, you do not need to be an HTML or CSS expert. You only need to have a basic understanding of HTML and/or CSS, or be wanting to learn HTML and CSS. If you're a student, then CSS HTML Validator is an excellent program to use for learning HTML.
CSS HTML Validator would not be for you if you don't have any knowledge of HTML/CSS *AND* you do not want to learn. If you do not have a basic knowledge of HTML and CSS, but you do want to learn, then we recommend combining an online HTML tutorial or book with CSS HTML Validator. If at first you find yourself overwhelmed with all the messages that HTML Validator generates, then don't worry, you'll quickly catch on after a few days of use. We think you'll quickly find CSS HTML Validator a valuable learning tool.
CSS HTML Validator for Microsoft Windows (formerly CSE HTML Validator) is a powerful, easy to use, user configurable, and all-in-one HTML, XHTML, and CSS checker that also includes an SEO (search engine optimization) checker, link checker, spell checker, accessibility checker, and built-in editor.
Just open an HTML, XHTML, or CSS document with CSS HTML Validator and tell it to do its thing by pressing F6! Easy to understand syntax errors, warning and other messages will appear below the source of your document. Simply click on one of these messages and you will be taken to the place in your document where the problem is. Fix the problem with the integrated editor, check the document again (to make sure that the problem is fixed), and then save it when you're finished.
The Batch Wizard, included in the professional edition, lets you easily check/validate multiple files and/or URLs and will generate a neatly formatted HTML report with the results. The Batch Wizard can follow links to check an entire small to medium sized web site or part of a large one. It also includes a spell checker and link checker.
If you think that you're writing clean HTML, then you'll be surprised at what CSS HTML Validator will find in your documents! CSS HTML Validator is an indispensable tool for any HTML author.

A free lite edition, CSE HTML Validator Lite, is also available (even though it has now been discontinued). This edition is less powerful than the paid editions, but it's free and can be used for commercial purposes. However, we don't recommend that professional web developers and businesses use this edition because the paid editions are significantly better.
Current versions of CSS HTML Validator require Windows Vista, Windows 7/8/8.1/10, or compatible OS. No other special hardware or software is needed.
