Conformance Statement for e-LfH
Our complete Accessibility Conformance Statement can be found on our website.
Accessible Style
We make efforts to support users of different forms of assistive technology (AT) by providing assistive text, subtitles and captions in our e-learning sessions, where appropriate. We also provide a high contrast version of our e-learning sessions for users with vision disabilities. This style can be enabled and disabled by selecting this icon Use high contrast stylesheet in the footer of the session.
Selecting the high contrast style switches off many colour options, making most of the content black and white. Alternative versions of some content is also provided, for instance where it would otherwise be difficult for users with visual impairments or for those users not using a mouse device.
e-Learning for Healthcare's aim is to make this e-learning session as usable and accessible as possible. Please contact us if you require further help, if you have any feedback, or if you would like to report any difficulties.

Table of Access Keys Used
Access keys are intended to provide an alternative form of navigation by using keyboard shortcuts. Please note that only numeric keys have been used in this e-learning session, in an effort to provide the alternative navigtation while not conflicting with any other software that may use access keys or any access keys already defined by the user themselves.
