Accessibility basics for Year 9

Alt text

• Every meaningful image needs alt text describing what it shows.
• If an image is decorative only, use alt="" so screen readers skip it.

Clear heading structure

• One <h1> per page, followed by <h2> and <h3> in order.
• Avoid skipping levels (do not jump from <h1> to <h4>).

Colour contrast

• Ensure text stands out from the background (dark text on a light background or vice versa).
• Avoid pairing light grey text on light colours.
• Test by printing in black and white; if it is still readable, contrast is likely acceptable.
