Website accessibility is a serious topic for all web developers these days, and if it isn’t, it should be. Making a website that is accessible is not that hard, but it does require you to think from a UI point of view instead of a pure coding thought process. One tool that is freely available for you to download is NonVisual Desktop Access (NVDA). The website describes it as this:

“Providing feedback via synthetic speech and Braille, it enables blind or vision impaired people to access computers running Windows for no more cost than a sighted person”

This tool can help you diagnose accessibility issues your website may have for blind or vision impaired users. It can help you diagnose input fields that can’t be read, missing alternate text for images and a bunch of other things. You can download this great piece of free software from here.
