1. Where is the easiest place to start in order to make my website or course accessible?
Begin with color contrast. This is the easiest change to make and will make a big difference.
Google Chrome browser has the Color Contrast Analyzer extension that can be added to your browser to check contrast. It's simple to use: click the icon on the toolbar and choose the evaluation level. Chart of contrast minimums: contrast minimums.docx

2. Is there anything else I can do to quickly update my website or course?
Yes. If the fonts that you have used are serif type, you can change to a sans-serif font such as: Verdana, Helvetica or Arial.

3. Why is it important to make my website or course accessible?
For starters, accessibility is not just for those with a permanent disability. It is for the elderly, those in rural or developing countries, as well as those with a situational or temporary disability. This means that any one of us may need accessibility at some point in our lives. What if you injured your hand or arm? How about if you needed to wear an eye patch? How would these injuries change the way you access the internet or do your school work?
Need more reasons? 315 million people in the world have color blindness. 39 million are blind, and another 246 million have low vision. These users need some form of accessibility.
