上海时时乐官网走势图:Using WAI Material: Permission to Use with Attribution

Introduction

W3C Web Accessibility Initiative (WAI) develops material to help make the web accessible to people with disabilities. As with all W3C material, WAI material is generally available for you to use, for free, with the two conditions below. For example, you can use WAI material by linking to it from your blog, putting it on a USB flash drive and handing it out at a conference, copying it on your intranet, printing it and handing it out to students, including it in a book, etc.

There are two conditions for using most WAI material; you must:

  1. Clearly attribute the original source as specified below, and
  2. Not modify the content (with few exceptions noted below).

Please read below for more details, including some material that is specially-marked content that you can modify.
