The Plymouth University website uses best-practice progressive enhancement techniques.
Of all the web technologies, HTML is the only one which will not fail. An individual browser may not support a specific tag, but the content will remain readable. HTML provides a baseline experience which can be viewed by all users regardless of device.
Progressive enhancement then applies additional technology layers when possible. For example:
- images, charts and diagrams are embedded within the document
- CSS is applied to style the page, for example, add fonts, spacing, colours, layout etc.
If any layer fails for any reason (browser support, network failure, timeout etc), the baseline content and functionality remain operable.
