We design to the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA: semantic headings and landmarks, keyboard-operable menus with visible focus, text that scales with your browser settings and pinch zoom, sufficient color contrast, and descriptive alternative text for images. Pages are available in English and Chinese.
Accessibility is ongoing work. If something on this site does not work for you, tell us and we will fix it.
One-tap presets for vision impairment, dyslexia and reading, ADHD and focus, seizure safety, and keyboard or motor needs.
Enlarge text up to 175%, widen line, letter and word spacing, change alignment, or switch to a readable font.
High-contrast, dark or inverted color modes, and grayscale or boosted saturation.
Highlight links, headings or the keyboard focus, enlarge the cursor, follow text with a reading guide or mask, stop animations, hide images, mute sounds.
Have the page read aloud with your browser's own speech engine, or jump to any heading or landmark from the page-structure list.
Keyboard shortcut: Alt + Shift + A. The panel is available in English and Chinese and follows the language of the page.
Your choices are saved only in your own browser and are never sent to PIV. The panel script is delivered by the jsDelivr content delivery network, which receives the technical request information needed to serve the file. The panel supplements, and does not replace, the accessibility built into the site itself, which works with screen readers, keyboard navigation and browser settings without it.
