struktuurimärgistuse

Struktuurimärgistus, commonly referred to as structural markup, is a system of using specific tags or codes within a document to define its organization and content hierarchy. It is distinct from presentational markup, which focuses on the visual appearance of text. Structural markup's primary goal is to semantically describe the role of different parts of a document, making it easier for both humans and machines to understand.

In the context of web development, HTML (HyperText Markup Language) is a prime example of structural markup. Tags like `<p>` for paragraph, `<h1>` for a main heading, and `<ul>` for an unordered list provide meaning to the content they enclose. This semantic structure allows for better accessibility, as screen readers can interpret the document's layout and provide a more coherent experience for visually impaired users. Search engines also rely on structural markup to understand the relevance and topic of web pages, influencing search rankings.

Beyond HTML, other systems employ structural markup. For instance, XML (eXtensible Markup Language) allows users to define their own custom tags, enabling the creation of highly structured documents for specific applications, such as data exchange or configuration files. The consistent application of structural markup facilitates data processing, reusability, and interoperability between different systems. Ultimately, structural markup prioritizes the meaning and organization of information over its aesthetic presentation.
