Use CSE HTML Validator Standard, Pro or Enterprise to help check for:
CSE HTML Validator Standard, Pro or Enterprise for Windows can be used to check web documents for issues that can affect accessibility, based on WCAG 1.0, WCAG 2.0, and/or Section 508 requirements.
NOTE: Be sure to turn accessibility checking on in the Accessibility section of the Validator Engine Options (go to). Read below for more information about accessibility and how CSE HTML Validator can help.
Section 508: For US government websites, CSE HTML Validator helps check for Section 508 compliance and has been purchased by many United States government organizations including the Social Security Administration, Federal Highway Administration, Centers for Disease Control, US Postal Service, Department of Argriculture, Department of Commerce, Department of Energy, Library of Congress, FDIC, NASA, NOAA, US Geological Survey, and the US Census Bureau.
Simply open your document (a CSS file or HTML file containing CSS) in the program, press F6, and your document is checked. It's that simple!
TIP: Don't settle for an accessibility checker that doesn't also check the HTML, XHTML, and CSS syntax of the page. An important characteristic of an accessible page is that it is free of syntax problems. CSE HTML Validator checks HTML/XHTML and CSS syntax in addition to checking for other accessibility issues.
When a web site is accessible, it means that anyone, regardless of ability, can enjoy and use the web site effectively. As an added bonus, it also makes the web site more machine readable, and that often has search engine benefits.
As an example, image a web site with many images on it (using the "img" element). A blind visitor may be using a screen reader or talking browser to "view" this page. One of the most significant (and very easy to do) actions a web developer can do to increase accessibility and make a web page accessible is to supply appropriate "alt" text for each image. This "alt" text is what the user's screen reader or talking browser will read to the blind user because he/she cannot see the images. If this "alt" text is not there, then the web page often becomes inaccessible to blind users.
As an example, consider an image on a product page that says "Buy Now" but there is no "alt" text for this image. Because there is no "alt" text, a blind user could easily get lost if they are trying to order the product. Instead, the image should have an "alt" attribute that is simply alt="Buy Now". This will let a screen reader or talking browser tell the blind user that the image is the order button, and the user will then know what to do to continue ordering the product. Without this simple addition, a blind user would not be able to use the web page as effectively as a user who is not disabled.
There are many reasons why you should make your web site accessible.
CSE HTML Validator generates many messages to help you make your web site more accessible. Furthermore, unlike other accessibility tools, CSE HTML Validator also generates messages about the syntax problems in your HTML, XHTML, and CSS documents. These syntax problems are often another source of accessibility problems. By utilizing CSE HTML Validator's syntax and accessibility messages, as well as user feedback and human site testing, you'll be well on your way toward having a quality, accessible web site.
Please note that although CSE HTML Validator is an indispensable tool for producing accessible web sites, no computer program can find all accessibility issues. Therefore, we highly recommends that you utilize human testing and feedback to find any problems that a computer program cannot find. Ensuring accessibility requires a significant amount of manual work. CSE HTML Validator helps reduce the amount of manual work to a minimum by quickly checking your documents and finding certain problems before your web site is manually tested.
