There are other ways that you can change text size on a web page. If you have a mouse with a scroll wheel, simply hold down the CTRL key - or the command key if you are a Mac user - and move the scroll wheel up and down. For Firefox users, hold down the CTRL key and press the plus (+) and minus (-) keys. Finally, if you are using Internet Explorer 7, you can hold down the CTRL key and press the plus or minus keys which will zoom the whole page in and out of view.

Accessible  Forms 

Ask anyone who has had to fix a web site that is littered with accessibility howlers, top-most in their list of problems encountered will be forms, closely followed by tables. These two topics always seem to present the most difficulties, but they needn't be a problem. For the most part, forms are a problem because the extra accessibility tags are simply not known to the web designer - after all, it looks right, it seems to work - what's the problem? Only by switching off the monitor and using a screen-reader can our oblivious web developer understand the problems.
