We’ve made accessibility a first-class, non-negotiable design philosophy. For us, accessibility is an ongoing practice rather than an endpoint, and we are committed to ensuring everyone using Manifold can access, engage with, and create content in meaningful and exciting ways. There are a lot of reasons why we made Manifold, and joy is an integral element in all of them. So when we talk about accessibility, we aren’t talking about simply “checking the accessibility box” for some imaginary person in a darkened back room. We earnestly want to create a platform where all readers—sighted, print-disabled, or otherwise—can have engaging and enjoyable experiences.
On this page, you can learn more about how the Manifold team works to meet these goals. We discuss accessibility strategies and compatibility in the following sections. If something here isn’t as clear as you’d like or you have additional questions, we’ve also provided our contact information. Please don’t hesitate to use it.
Development and Design. All user interface design that we do follows WCAG’s guidelines for visual elements. We make sure all elements have adequate color contrast and text size, that interactive elements are large enough for touch interaction, and that visual indicators are included for element states like hover and focus.
When those interfaces are built, developers begin with a foundation of semantic HTML. We supplement this with ARIA to ensure that the structure, contents, and state of the application are fully conveyed to assistive technologies. In addition, we include predictable keyboard controls for all interactive widgets and low-motion alternatives for all animations. To give us confidence in our approach, we lean on established design patterns and best practices.
Developers also give priority attention to reports of existing bugs in the application and work directly with Manifold users in GitHub to define and implement solutions.
In all of our work, we use a broad set of testing tools and strategies. We employ software like Sim Daltonism, Accessibility Insights for Web, and Lighthouse for automated tests. We also do thorough manual evaluation of our work that includes, but is not limited to, keyboard navigation, zooming, reduced-motion mode browsing, and screen reader interaction with VoiceOver and NVDA. As one final check, all code we write must pass an accessibility-focused code linter before it is merged and deployed.
Partnerships. We partner with colleagues such as the University of Washington Libraries and Accessible Technology Services to conduct regular accessibility reviews of Manifold and to discuss issues of accessibility more generally.
Standards Compliance. We aim to have the Manifold platform meet the latest WCAG 2 AA Standards (currently WCAG 2.1 AA).
Education. We work with Manifold publishers to encourage them to create accessible source materials so that publications on Manifold will be accessible.
In library views and within the Manifold reader, the application can be navigated and interacted with using the expected keyboard controls. Where appropriate, Manifold will deliver context-specific instruction to users when they focus on elements so they know how to perform an action in that space.
- Tab advances focus forward, left to right and down the page
- Shift + Tab moves focus backward, right to left and up the page
- Enter or Return selects
- Space or Page Down advance the view down the page by a screen view
- Page Up moves the view back up the page by a screen view
- Up and Down keys adjust the view forward or backward by line
- Home and End move view to the top or bottom of the page
- Drag and drop elements can be selected using the space bar and reordered using the arrow keys.
- YouTube and Vimeo video resources can be navigated using the keyboard commands of those respective apps. Refer to the documentation from YouTube or Vimeo for more.
- Manifold’s audio and video players do not currently support keyboard functionality.
- Interactive resources are remotely hosted content and beyond the scope of what Manifold can control. If publishers use platforms that have keyboard functionality, that same functionality will be included in the Manifold experience.
Manifold is distributed software that is used by many different publishers and groups. We work diligently to ensure the application is itself accessible and can render standards-compliant accessibility frameworks and metadata to assistive technology in the expected ways. However, the obligation of creating accessible content falls to those who maintain their own Manifold instance.
