Using Paragraph and Character Styles
InDesign has Styles that help determine what tags are assigned to elements, which ensures greater accessibility when exported to a PDF. Styles also help maintain consistency within your document and make overall format changes easier.
- From the main menu, select Type.
- Select Paragraph Styles. To bookmark the panel, drag and dock it into the panel sidebar.
- Paragraph styles can be used to style blocks of text; character styles are used for individual words or a sentence within a paragraph.
-
Open the Paragraph Styles panel. Select the Create a New Style icon (at the bottom of the panel, next to the trash can).
- A new style called Paragraph Style 1 will appear in the list. Right-click on it then choose Edit.
- Rename the style to reflect what you are styling, such as body copy, heading 1, sidebar, etc.
- Using the various tabs on the side, style your text as desired. Any text that has that Paragraph Style applied will reflect the style choices that are set.
- Basic Character Formats tab:
- Choose the font family, font style and font size
- Indents & Spacing tab:
- Set alignment and any indentation
- Hyphenation tab:
- Uncheck hyphenation box to turn it off
- Span Columns
- Set number and layout of columns
- Bullets & Numbering tab:
- Set the list type, bullet character or numbering style
- Character Color tab:
- Choose a color. Be sure to double-check contrast ratios using the WebAIM checker
- Export Tagging tab:
- Tags content appropriately to ensure greater accessibility when exported to a PDF
- At the bottom of the dialog box, under PDF, choose the appropriate tag for that style
- Select OK to save style choices
- Basic Character Formats tab:
- Highlight text to be styled and choose the appropriate Paragraph Style to apply.
Setting a Character Style is a very similar process. Character Styles are used for individual words or a sentence within a paragraph.
- Open the Character Styles panel. Select the Create a New Style icon (at the bottom of the panel, next to the trash can)
- Using the various tabs on the side, style your text as desired. Any text that has that Character Style applied will reflect the style choices that are set.
- Highlight text to be styled and choose the appropriate Character Style to apply.
Text Equivalents with Alt Text
All images and objects in an InDesign file should have alternative text assigned.
- Highlight object
- From the main menu, choose Object
- Choose Object Export Options
- Choose the Alt Text tab, then from Alt Text Source drop-down, choose Custom. Type alt text into the box
- Select Done to save
Provide Descriptive Hyperlinks
Hyperlinks in an electronic document should be embedded within the text to aid in readability and accessibility. Imagine you have the sentence “I work at SUNY Oswego” in your document and you want the words SUNY Oswego to link directly to the college’s website.
- Select the text you would like to convert to a hyperlink (in this example, SUNY Oswego).
- From the main menu, select Type.
- Select Hyperlinks & Cross Reference, then choose Hyperlink.
- A dialog box will open. In the Link To drop-down, choose URL.
- You could also choose to link to another file, an email address, a page within the document, etc. The Destination drop-down menu will change according to this selection.
- Enter the URL under Destination.
- You can assign a Character Style or create a new style. From the drop-down menu, select the Character Style or choose New Character Style.
- Click OK to save.
Adding Metadata
Adding metadata helps prevent some accessibility issues when exported to a PDF, and also can be used for SEO (Search Engine Optimization) of digital documents. In this section, we are just focusing on accessibility.
- From the main menu, select File.
- Select File Info.
- From the Basic tab, enter a title for the document. Accessibility checkers look for document titles. The other metadata is mostly used for SEO.
Specify the Reading Order
InDesign does not automatically know the correct reading order of the content. Therefore, before exporting an InDesign file, the reading order should be manually set.
- From the main menu, select Window, then Articles
- The Articles panel will open and be empty
- Content must be added to the Articles panel, in the order it should be read.
- Be sure the selection tool is highlighted in the tool bar.
- Drag and drop the content, in the correct reading order, to the Articles panel. There are two ways to do this:
- With the selection tool, highlight the content one piece at a time and drag it to the Articles panel.
- Or, hold the Shift key and highlight multiple pieces of content using the selection tool. Be sure to highlight them in the correct reading order. Drag the group to the Articles panel.
- The content will appear as a list in the Articles panel. This is the order that assistive technology will read the content. You may drag and drop each piece to rearrange the order, if needed.
- Repeat this process for each page of the file.
Saving as an Accessible File
Using the Save As feature will not capture accessibility information. Use the Export option instead.
- From the main menu, select File, then Export.
- Navigate to where you’d like the file saved, enter the file name, and set Save As type as Adobe PDF Print.
- Select Save.
- An InDesign dialog box will appear.
- From the General tab, enable the Create Tagged PDF check box.
- If PDF will be available on the web, enable the Optimize for Fast Web View, Hyperlinks and Bookmark checkboxes.
- From the Advanced tab, select the Document Title option under the Display Title drop-down. Choose the appropriate language.
- To save these settings for each time you export to PDF, click the Save Preset button in the lower-left corner of the Export dialog box. Name the preset.
- In the future, to retrieve these settings, choose the appropriate setting title from the Adobe PDF Preset drop-down menu.
- Select Export when finished.
Finish with Adobe Acrobat
After the PDF is exported, it's always a good idea to double-check the accessibility of the document using Adobe Acrobat Pro.
- Open your PDF using Adobe Acrobat. Go to the Tools menu, then go to the Customize section, and choose Action Wizard.
- An Action List will open in the right-hand sidebar. Choose the Make Accessible option, then Start.
- Answer the prompts as appropriate.
