91Èȱ¬

To make good choices about HTML document structure and development approach, a well-defined core purpose is needed. The 91Èȱ¬ mission, to inform, educate, and entertain, should be the foundation of this core purpose. Without purpose, there would be no reason for site or document.

Why it matters

While our aim is for all users to access all features of 91Èȱ¬ websites and apps, it is recognised that technology both restricts and extends what is possible. In providing the best experience to the broadest range of users, we should neither discriminate against users with access needs nor give one group special privilege over another.

Defining a core purpose helps to prioritise which aspects of an experience need to be accessible across the broadest range of technologies. The core content would be those elements that fulfil the core purpose of the document. The accessibility of non-core page elements still matters.

See the following recommendations for examples of when a defined core purpose is helpful:

• Progressive enhancement
• Minimum text size
