Do you own a website for a long time?
If yes, then you know everything about ADA compliance. How to incorporate these guidelines into website structure and what is their significance; you are aware of everything.
However, 如果你打算创建一个新的网站或更新现有的网站(如果没有可访问的网站), 那么你应该在你的网站设计和开发中加入ADA标准，以便为你的用户提供一个可访问的网站.
ADA指南分为A级、AA级和AAA级三个级别. Out of which level A is the lowest conformance level, AAA is the highest one, AA级是中级水平，如果你希望有一个可访问的网站，这是最低要求.
Thereby, we will discuss level AA here in this article. 如果你坚持AA级，你的网站将被视为一个可访问的网站 avoid every type of ADA lawsuit.
Achieving ADA conformance level AA
这个层次是符合和保持设计灵活性之间的平衡. 有些要求可能有点复杂，但它们将帮助您避免昂贵的诉讼. 这里有一些重要的指导方针，需要包括在网站架构.
1. Audio description is a must for video content (pre-recorded)
When you add audio narratives, 你让视障人士也能访问视频内容. 确保声音清晰，与视频同步，以便更好地理解. 此外，提供其他用户可以听到的每一个小细节.
2. Color contrast should be 4.5:1
根据AA级指南，文本和背景之间的对比度预计为4.5:1 for clear visibility. 这意味着如果使用深色背景，尽量使用浅色文本，反之亦然. The ratio depends on the size of the fonts as well. For smaller fonts, it is 4.5:1 and for bigger fonts, 3:1 is to be followed. Typography must be compliant; you should avoid using stylish fonts that are hard to read.
3. Resizing of text without losing the main content or function
有一些用户发现由于字母的大小，一些单词或内容难以阅读. 因此，为了使这些用户能够阅读，必须有一个文本大小调整选项. 如果需要，用户可以将单词的大小调整到200%，而不会丢失内容. 不要忘记在不同的浏览器和设备上测试此功能，以确保其一致性.
4. Easy Navigation
The navigation of a website impacts its UX design and accessibility. It is a crucial facet of a successful website. 确保提供简单多样的方式来浏览网站页面. Sitemaps, a clear and simple navigation menu, and a search tab on every page can be some good options. 改善导航的另一种方法是在内容相似的页面上添加“相关页面”. These elements fine-tune the website’s navigation for sure.
5. Menus, icons, and buttons must be consistent
在页面上使用元素很重要，也很有必要，但要确保在每个页面上都以一致的方式使用这些元素. 相似的图标或按钮必须以相同的顺序或在每个页面上的位置，以避免混淆.
6. Images require to have alt text
If using images on the page, 它们必须有清晰的Alt文本，因为Alt文本可以帮助辅助设备理解图像以及它们在内容中使用的原因.
7. Add transcripts to audio files (pre-recorded)
与视频内容一样，音频文件也需要有清晰的文字记录. There are users who cannot hear the content, they take the help of these transcripts to understand the audio. 此外，在一个嘈杂的地方或如果一个人不想打开音量，它是有用的.
8. Headings must be in a logical order
所有的标题应该按照逻辑顺序排列，以便辅助设备可以很容易地理解它们. 如果标题和副标题乱七八糟，对依赖这些技术的用户来说没有意义，他们就无法阅读你的内容.

9. Forms and their all fields should be labelled properly
If the website contains forms, they should be accessible. Ensure all the fields are labelled rightly.
10. Whenever needed, provide suggestions to understand errors
为了纠正错误，在你的网站上提供适当的建议. 如果一个有认知障碍的用户在浏览你的网站时输入了一些错误的信息, 他们必须得到正确的错误信息，以便他们能够理解犯了什么错误.
11. Captions for real-time media
There must be captions for live streaming audio-video content. 为了让有听力问题的用户更全面，字幕会有所帮助.
12. Focus visible for navigation through the keyboard
Many users cannot navigate the website using a mouse. 他们在键盘上导航时需要一个视觉焦点指示器. Without this visual indicator, 它们可能在理解与哪个元素交互时遇到问题.
13. Proper switching to languages of parts
If the content switches its language in a section, 后端必须有规范来加载适当的值，以便浏览器和辅助技术能够正确地解释它们.
14. Error prevention
Anybody can make mistakes while giving inputs or submitting forms. There should be some ways to reverse such mistakes, especially in the case of legal or financial matters. By allowing a user to correct input errors, or reverse a submission, you help them to avoid many consequences of such blunders.
