So what? Tell me more about #accessibility, please.
Accessibility is the practice of making your products or services usable by as many people as possible.
We traditionally think of this as being about people with disabilities, like Wikipedia told us, but, the practice of making services accessible for everyone, also benefits other groups making design and code clean and simple.
You may also think of accessibility as treating everyone the same, and giving them equal opportunities, no matter what their ability or circumstances, always making them feeling unique, adding value to any product and service you give.
