Accessibility

The guide is made of plain HTML pages with a little script. Text can be enlarged well beyond its normal size without loss, pages reflow on narrow screens, and reader modes and browser translation work.

The district finder

The finder is a single labelled drop-down list of the 14 councils. Choosing one writes the result into an area that screen readers announce politely, without moving focus. The same facts for every council are also written out in full lower on the page, so nothing depends on the script running.

The district grid

The grid of coloured window panes on the home page and district pages is a set of ordinary links, one per council, each named after its council and opening the district finder at it. The pane colours repeat the off-gas share shown in text inside each pane; colour is never the only signal.

Rolling figures and animated headings

Some headline figures count up when they scroll into view, and one heading on the home page reveals word by word. Screen readers are given the final figure and the whole heading straight away, and the moving copy is hidden from them. If your device asks for reduced motion, the figures and heading appear in their final state with no movement.

Tables

Data tables have captions naming their sources, header cells for rows and columns, and sit in a labelled scrolling region that can be reached with the Tab key and scrolled with the arrow keys on a small screen.

Menus and forms

The header menus open with a keyboard, and the current page is marked for screen readers. The question form at the foot of most pages has a visible label on every field, and the browser's own checks name any field that needs attention.

Known limits

The diagrams, such as the plan of a row of terraces, are images with full text descriptions; the same points are made in the page text. Some linked sources, especially government spreadsheets, may be harder to use with assistive technology than this site.
