Accessibility and comfort options

Press Alt and U to open the panel. Use Tab to move between controls. Use Escape to close the panel.

When you open a section, the page should scroll so the new content is visible.

Drag the floating button to a corner so it does not cover anything important. If you prefer a fixed position, use the position presets inside the panel.

None of these settings change your course progress.

If long pages feel tiring, try read aloud, link highlighting, and spacing controls. You can also switch on a reading mask to keep your place.

The panel includes a short help chat for website navigation, plus a page structure list.

If something is confusing, please report it. I would rather fix the page than make you wrestle it.

I aim to meet WCAG 2.2 AA where it is practical. This site mixes content, tools, and interactive labs, so the work is ongoing.

If you rely on a particular setup, for example a screen reader or keyboard only navigation, your feedback is genuinely useful.

• Clear page structure with headings and sensible reading order.
• Keyboard navigation for key interactions.
• Colour contrast designed for readability, including dark mode where available.
• Reduced motion support for people who prefer fewer animations.

• Some interactive labs use custom UI that may need extra screen reader hints.
• Speech synthesis quality varies by browser and device.
• Some older pages are being refreshed to match the newer layout and controls.

If you spot an accessibility problem, please tell me what page you were on, what you were trying to do, and what happened. If you can, include your browser and any assistive technology.
