A good website should outlast its framework
Stable links, readable documents and shared standards remain valuable even as the tools used to build websites keep changing.

A website is often discussed in terms of the software used to build it. For a reader, the more durable questions are simpler: does the address work, is the document readable, and can the information be found again? Those qualities deserve attention before the next redesign.
Shared web standards provide a foundation for continuity across devices and implementations. HTML gives a document structure, CSS controls presentation, and accessibility work helps more people use the result. None of that guarantees longevity, but it reduces dependence on a single company's preferred tool.
For a publication, maintaining old links can be as important as adding new features. Preserve article addresses, provide meaningful headings and keep the essential text available without unnecessary obstacles. A useful archive is a continuing service to readers, even when the machinery behind it has changed completely.
