Use of images

All non-decorative images should provide a text alternative for assistive technologies such as screen readers to interpret.


All forms should be properly structured with label descriptors for identifying the input form elements.

Access keys

Use of access keys have previously interfered with screen readers and browsers. While no standard exists for globally recognised reserved keys, and each website can differ with their usage, we do not use this practice however we continue to monitor this development.

Colour contrast

Site design has been built and tested against acceptable color thresholds for users with low vision impairment.
