Are the links free of any validation errors? (LNK22)
Why Is This Important?
There are a number of reasons for ensuring that a webpage validates against formal specifications:
- To ensure that the webpage is rendered consistently across different platforms and user-agents. This includes assistive technology, such as screen readers, which rely on the appropriate semantic markup.
- To ensure that the webpage is future-proof and does not rely upon the rendering quirks of contemporary web browsers.
- To make the webpage easier to maintain. Conforming to a common standard makes websites easier to understand and maintain, either by the original author or someone else.
- To demonstrate good practice and professionalism by incorporating good, semantic, well-formed markup.
How To Fix The Problem
The W3C provide a range of validation tools for common web technologies. Webpages can be validated either be entering a URI, uploading a file, or by entering the code directly. Depending on the validity of the code, this may return a number of errors or warnings, along with suggestions on how to fix the problem.
