Web Accessibility Toolbar - Version 2.0 (Posted June 15, 2007)
The Web Accessibility Toolbar is the best thing that has happened for accessibility in recent years. Steve Faulkner at The Paciello Group and JUn at WAT-C have made some very important improvements and additions for Version 2.0 of the Web Accessibility Toolbar which is currently in Beta.
Many of the functions from the first version of the Web Accessibility Toolbar are improved and debugged. One of my favorite enhancements is the fact that the functions now operate on the content of frames and iframes transparently. For example, try the Headings function with the current Accessibility Toolbar on the Travelocity web site, the result will be an alert saying that The page contains iFrames, Headings cannot be shown. Not any more.
One welcome addition is an alert after execution of the many of the functions, including Show Images, which states the number of images with no alt-text, this is the number of certain errors and it is now up to the reviewer to check the quality of alt-text on other images.. The alert includes the URL of the page being verified as shown in the following screenshot.
The toolbar itself is simpler and beautifully organized. The following screenshots show its current incarnation.
The toolbar consists of a series of fifteen buttons, many of which bring down menus of functions as illustrated above where the menu for Frames is open and in that menu, the submenu for navigate to framed documents is also open. The buttons are:
- WAT - Documentation and update function
- Check - Validation tools including a Quick Check which returns the number of errors from the W3C HTML validation site in an alert box without having to display the Validator page
- Resize - Various options to resize the browser window
- CSS - Options to Disable CSS or certain parts of CSS
- Images - Various options to explore the at-text of images including Remove Images which used to be called Toggle Images and Alt; it just replaces each image with its alt-text or "No alt"
- Colour - Options to test for contrast or view in Greyscale
- Structure - Functions to analyze (i.e. highlight) the semantic markup on the page, including headings and lists
- Tables - This is separated out from Structure in the previous version. That definitely is helpful because the Structure menu had become too long
- Frames - From the Frames menu you can navigate to specific
frames or get a list of
iframeelements including important
- Source - Pretty much the same functions as before, one that I had not noticed, however, and will use it a lot. The Highlight Source menu allows you to specify which elements you are interested in (I will use Forms a lot), and then the source code is displayed with those elements highlighted. Terrific. I wonder what other gems I have missed.
- IE - A menu of easy to access standard IE accessibility functions like Text size.
- Log - A one and very impressive. Press the Log button and a small edit area opens at the top of the browser. Functions add information and you can type information, and save the results. What a terrific idea. I would put a lot more information. For example, if you Show Images and all images have alt-text, nothing gets entered in the log. It should be, the URL and "0 alt text errors".
- FireFox - Open the current page in Firefox - how cool is that!
- Opera - Open the current page in Opera!
Detailed Menu by Menu documentation is available on the TPG web site. Congratulations Steve!
