märgistuselemendid

Märgistuselemendid, also known as markup elements, are the fundamental building blocks of markup languages. They are used to define the structure and content of a document. These elements typically consist of a start tag, content, and an end tag, although some elements, like empty elements, do not have content or an end tag. The start tag usually encloses the element name, often within angle brackets, and may include attributes that provide additional information about the element. The end tag is similar to the start tag but includes a forward slash before the element name.

The purpose of märgistuselemendid is to semantically annotate text, distinguishing between different parts of a document and indicating their role or meaning. For example, in HTML, elements like `<p>` for paragraph, `<h1>` for a main heading, and `<img>` for an image are used to structure web pages. Similarly, XML uses elements to create custom, structured data formats. These elements allow software applications to interpret and process the document's content correctly, enabling features like rendering, searching, and data exchange. The hierarchical nature of markup languages means elements can be nested within one another, forming a tree-like structure that represents the document's organization.
