It is imperative that website admins ensure their content is accessible. Borrowing from the Accessibility at Johns Hopkins University website, here are a few quick ways to ensure your website’s content is accessible:
- All media (video, audio, images) on all pages in your site should have alternative text descriptions.
- All pages should be designed around the principle of distinguishability.
- Each page in your site should be fully readable by a screen reader.
The Web Services Team reserves the right to edit or remove any content or images that fails the World Wide Web Consortium Web Content Accessibility Guidelines, version 2.1 Level AA conformance.
All images must contain alt text to satisfy accessibility requirements. These describe the appearance and function of an image on a page. Images that do not have alternative text descriptions will be removed without notice.
- Images that are uploaded via the text editor and don’t have an alternative text description will have an image appear prompting you to add a alt description.
- Images that are missing alternative text descriptions will have a red dashed box around them when viewing the page logged in.
Examples of each scenario are below:
PDFs of scanned book pages or posters, and other PDFS that are not machine-readable, are accessibility violations because a screen reader cannot read the words on the page. Making a document machine-readable allows users to search the contents of the PDF, and copy and paste its text. It also enables screen-reader users to access the content.
We suggest reading WebAIM’s tutorial on PDF Accessibility in addition to following these tips to create accessible PDFs:
Create Accessible PDFs from Microsoft Word Documents or PowerPoint
- Save as an Adobe PDF
- Identify the document language
- Use the Touchup Reading Order feature
Create Accessible PDFs from Scanned Documents
- This requires Adobe Acrobat Pro, which is available on most computers.
- Open your non-editable PDF document in Acrobat Pro and click on the “Tools” option. In the sidebar, select Text Recognition and then select “In This File”. Click ok on modal popup.
- Save file and replace it on your website
Enabling password protection on a pdf file is not allowed due to quality assurance and accessibility issues. Users should place sensitive and secure documents on a University IT-approved tool, and set appropriate permissions therein.
Note: The KSAS Web Team reserves the right to remove PDFs that are not machine-readable or have passwords without notice.
PDF Uploads in Forms
Because all Krieger Web Properties are on a public web server, they are indexable by google and other search engines. Therefore admins should not create forms with fields that require or request file uploads that may violate FERPA, HIPAA, or other privacy laws. These files include unofficial transcripts, health records, or any other sensitive information. It is the responsibility of the form-builder to capture that information more securely, either directly or via another form builder solution.
