Accessibility

We aim to make Water Vapor Pressure usable by everyone, and hold the interface to WCAG 2.2 AA.

• The calculator is keyboard-operable with a visible focus indicator on every control.
• A “Skip to content” link and semantic landmarks support screen-reader navigation.
• Results and the comparison table are real text (selectable, copyable, readable by assistive tech).
• Light and dark themes follow your system preference and can be toggled.

If you hit an accessibility barrier, please tell us on the contact page — we treat these as priority fixes.
