If You Can’t Navigate It, You Can’t Use It
Accessibility isn’t just about being able to see content — it’s also about being able to interact with it. That’s the second principle of accessibility: Operable.
If someone tries to use your document with a keyboard or screen reader, can they get through it easily?
What “Operable” Means (in Plain English)
To be operable, your document must:
- Let users navigate with keyboard controls (like the tab key)
- Follow a logical tab and reading order
- Avoid content that causes confusion or seizures (like flashing)
- Label form fields and interactive elements clearly
Your Recipe to Make Content Operable
Step 1: Use real heading styles
Avoid bolded text — apply actual H1, H2, etc., to guide navigation.
Step 2: Set tab order and bookmarks in PDFs
Ensure screen readers move through content in the correct order.
Step 3: Make all form fields accessible
Use labels, instructions, and logical tab flow for every input.
Step 4: Avoid flashing elements
Rapid movement or flickering visuals can trigger seizures or overwhelm users.
