When writing the code that creates a webpage (authoring),
content (text, images, etc.), is marked-up into elements.
Element types include: headings, tables, images and lists. For
example, to indicate that words within a sentence have
particular significance, they are marked-up as an emphasis
element; <p>If you remember nothing else, remember this <em>word
or phrase</em>.</p> The above markup is displayed as: If you
remember nothing else, remember this word or phrase. To view the
code used to create this (or any other) webpage, with the
webpage visible in the web browser, from the menu at the top of
the screen, select View > Source/Page Source. Markup that, at
some level, describes or affects the meaning of content is
referred to as semantic markup. In X(HTML) code, tags provide
the syntax for defining (marking-up) the beginning and end of
elements. How content is marked-up defines; An emerging
alternative use of the term ‘tag’ is to describe the
classification of content by readers (rather than the author). F
