Microsoft Word Tips

Upgrade Your Software

Upgrade to the most recent version of Microsoft Word. If you have MS Word 2016 or later, you should have a "Check Accessibility" option under the "Review" tab. Use 此工具用于识别和纠正MS Word识别的常见可访问性问题. 在保存之后，您仍然需要检查和更正一些内容 将你的Word文档转换成PDF格式，但这可以大大减少你的工作量 need to do once you get there. 

Use Headings Correctly

Use document headings for structure, not style. 最常见的可访问性错误之一是为了样式目的而使用标题 (e.g. to make text look bigger and bolder or a particular color). If you would like your text to look a certain way, use the text formatting tools such as font size, bold, italic, etc. directly. Or you can create custom styles using the Styles pane. Just don't use Headings such as Heading 1, 2, 3, etc. for cosmetic purposes.

Why You Shouldn't Use Headings for Styling Purposes

屏幕阅读器技术使用标题来传达内容的结构和组织 a document to its users. Headings, such as Heading 1, Heading 2, etc. create document structure in the same way that a table of contents is organized. Word (as well as Google Docs) can auto-generate a table of contents for your document based on its headings. It will assume Heading 1 blocks are like "chapters" and will nest Heading 2块作为标题1之前的子部分(标题3以此类推).). The bottom line is that Headings need to be nested properly to be accessible.

Properly Nesting Headings

Think of Headings the Same Way You Think of an Outline:

• Heading 1 is the first tier of bullets in an outline such as this.
  • Heading 2 is like any second-level bullet. In an outline, you can't skip to a third-level bullet without a second-level before it. Likewise, you should never skip a heading level in your documents. Doing so will create an accessibility issue.
    • Heading 3 can only exist after level 2 and so on.
  • Heading 2: You can come back from level 3 to level 2…
  • Heading 2: ...并且在内容需要的情况下，尽可能多地使用相同级别的标题. Note that you could also return to a Heading 1 from a Heading 3, just not the other way around, just like this outline.
• Returning to a Heading 1 signifies a whole new "chapter" or section of your content. 

Use Tables for Data, Not Layout

Use tables for data only, not for layout. Another common mistake that makes accessibility 在pdf中遇到的一个挑战是，当使用表格可视化地布局文本中的内容时 particular way. Tables should only be used for their intended purpose – to display content within a grid of columns and rows identified by column headers. Every column must have a header labeling the content of that column.

Adobe Acrobat Pro Tips

注意:如果你直接跳到这里，跳过了上面的Microsoft Word提示部分， please go back and review that section. Unless you have very few minor edits to an existing 508-compliant PDF，你总是想从头开始在一个新的Word文档和“另存为”PDF – you'll be thankful that you did. 

Upgrade Your Software

Obtain, or upgrade to, the most recent version of Adobe Acrobat Pro. The built-in 辅助功能检查器和它的一些自动任务，这可以帮助你 您的PDF 508兼容，在最近的版本中有显着改进，应该 save you considerable time and frustration compared with older versions.

Fixing Your PDF Accessibility Issues

The number and difficulty level of issues you may encounter can vary greatly. However, 如果我们只是在讨论纯文本文档，并且您已经遵循了所有提示 in this primer thus far, you're probably going to have minimal work to do. This guide 将不尝试解决众多的，有时是高度技术性的，修复 most PDF issues. Instead, we will cover a couple of common and simple quick fixes for a typical basic document.

Adobe Acrobat Pro has extensive documentation covering each of the issues you may encounter and this information can be easily found by right-clicking on any issue and selecting "Explain" from the context menu. This will open a new tab in a browser and should scroll to the specific issue in the Acrobat User Guide. At the time of writing, that user guide can be found at http://helpx.adobe.com/acrobat/user-guide.html，相关信息在标题为无障碍、标签、 And Reflow.

Fix the Title

标题不仅告诉你的用户这个文档是十大靠谱棋牌游戏什么的，而且它也成为 the text for the link that a Google search finds. Often a converted Microsoft Word document inserts the title with the .docx extension and whatever other random file-naming conventions we have come up with. So even if this one passes, it's a good idea to go in there and clean it up.

To check and update your PDF title, open up the main application's File menu, and select Properties. In the Properties dialog, the default view is Description, and right there at the top is the Title. Check that it reads just as a title should, removing any dates, file extensions, underscores, or any other unnecessary characters.

提示:即使你将此文档发布到PCC网页，谷歌和其他 search engines will still find it outside of this context so it's good to include “PCC”或“PACCD”在标题的某个地方，除了你的文档的标题. 

一旦更新了标题(以及可选的作者、主题和关键字)，单击 OK. Now go back to the Accessibility Checker results and right-click the "Title - Failed" error and select Fix. The check mark should turn green. Now don't forget to 保存PDF (Windows上是Control+S, Mac上是Command+S)，这样修复就会被保存 else checks your PDF for accessibility issues later. 

Fix Alternate Text

如果你没有根据本文第1部分的提示通过Microsoft Word添加备用文本 primer, you'll still have an opportunity to do it here. Expand the Alternate Text category and right-click on the "Figures alternate text - Failed" issue. Select Fix 从上下文菜单中，您将看到一个允许您添加 alternate text for every figure (image) that is missing it. Just add brief descriptive text in the text box provided and then either advance to the next image using the arrow button or click "Save and Exit." If you used the Decorative Image checkbox during the previous step, you may have a new set of errors after exiting this dialog. We recommend always including alternate text for each issue to avoid this quirk. Again, 一旦你纠正了这里的所有问题，你得到了绿色的复选标记，保存 PDF (Control+S on Windows, Command+S on Mac)
