Making Canvas and Websites Accessible: 什么不起作用

The following list consists of the most common issues that make web and social media content inaccessible 以及如何避免它们的快速步骤:

• Providing non-text materials without a text alternative; images, video, audio, and other non-text content are inaccessible without a text alternative
  • 相反:提供文本描述, 标题, 成绩单, 或者非文本材料旁边的其他文本
• Providing directions that rely on sensory characteristics; phrases like “to the right” or “the blue circle” have little or no value for students using screen readers
  • Instead: use the specific name of an element and its location in comparison to other elements
• Using images of text (exception: logo types); including text as an image creates an unnecessary layer of inaccessibility
  • Instead: remove the image and replace it with text
• Using color or underline as the only means of conveying meaning or importance; visual indicators are inaccessible to many readers
  • Instead: use programmatically determinable styles and labels to support visual indicators.
• 使用成语, 俗语, or jargon outside of topic specific terminology; language that is unclear, 模糊的, or irrelevant can create a barrier for many readers.
  • Instead: use clear and precise language appropriate for the anticipated knowledge level of the reader.
  • Idioms and 俗语 for stylistic purposes should be defined for clarity.
• 将链接显示为完整的url, 模棱两可的单词, or repetitive phrases; using language such as “click here” makes links difficult to identify for all readers, and full URLs are difficult to for almost everyone to read.
  • Instead: use short phrases that indicate the purpose or destination of the link
  • Exception: Physical documents need full URLs; the purpose of the URL should be indicated within the context, and some URLs may need to be shortened for full accessibility.
