Accessibility

Our approach

We aim to make this website usable with keyboards, screen readers and a range of screen sizes. Pages use structured headings, descriptive links and visible keyboard focus. We aim for readable colour contrast and provide text alongside technical graphics.

Using the website

Use the Skip to content link to bypass navigation. Menus and forms support keyboard interaction. Technical diagrams include text explanations, and chart figures are available in a data table. You can enlarge text using your browser controls.

Motion and media

Animations respect reduced-motion preferences. When an optional muted decorative homepage loop is supplied, visible play and pause controls are provided, with a static poster for reduced motion. The current edition has no hero video configured.

The explanatory SNG video uses manual playback controls. The process diagram and written descriptions provide its text alternative.
