Project 1 of H590, Spring 2018

The web accessibility evaluation was performed on a "wipro.com". I used the wave tool to recognize the errors related to accessibility and manually by inspect element and voice over. It was interesting to understand the various accessibility errors related to the website like missing <h1> tag and alternative text for some images. I also found out the color contrast problem and suggested solution to them. Making this report, I understood the basic accessibility errors a website could have and how they could be easily solved if paid attention to. With the help of this project, I understood the W3C standards for accessibility.
