Polyfills (link)

A polyfill is a piece of code (usually JavaScript on the Web) used to provide modern functionality on older browsers that 1) do not natively support it or 2) browsers implement the same features in different ways

Accessibility supported (link)

1. The way that the web content technology is used must be supported by users' assistive technology (AT). This means that the way that the technology is used has been tested for interoperability with users' assistive technology in the human language(s) of the content,

   AND

2. The Web content technology must have accessibility-supported user agents that are available to users. This means that at least one of the following four statements is true:

   | The technology is supported natively in widely-distributed user agents that are also accessibility supported (such as HTML and CSS); | The technology is supported in a widely-distributed plug-in that is also accessibility supported; | The content is available in a closed environment, such as a university or corporate network, where the user agent required by the technology and used by the organization is also accessibility supported; | The user agent(s) that support the technology are accessibility supported and are available for download or purchase in a way that:

    ◦ does not cost a person with a disability any more than a person without a disability **and**
    ◦ is as easy to find and obtain for a person with a disability as it is for a person without disabilities. |
