How is a tag in HTML used?

Answer 1

An HTML tag may be an opening tag, or a closing tag, if a closing tag is required for the element. An opening tag consists of an element surrounded by angle brackets, and may optionally contain attributes as well. A closing tag, if it is nessary or optional for that element, contains a back-slash before the element, to distinguish it from the opening tag.

H1, P, FORM are all elements, while <H1>, <P> and <FORM> are all tags. There is no H1 tag, only an H1 element.

Elements make up the structure of an HTML document. Attributes compliment the elements, eg: <p class="something">This paragraph as a different class attribute.</p>

Answer 2

We use tags in HTML to define what kind of data we're dealing with. Tags are used to set apart things like lists, headings, and paragraphs. They are also used to separate the meta data contained in the HTML documents HEAD with the actual content of the page, contained in the BODY.

The key part is that information regards what the data isnot how the data will be displayed. The older versions of HTML muddied the waters on this principle. But the current versions borrow from XML the concept that page structure is separate from presentation.

Answer 3

Tags are mainly comprised of an opening tag < > to indicate the start of the affected area, and a closing tag to indicate where the affected area ends. For instance, this text is bold, would be written in HTML as: this text is bold.

HTML tags can also be nested within each other, for example:

This text is bold and italic, but this text is only italic.

would be written in HTML as:

This text is bold and italic, but this text is only italic.

Which tag is used first in this instance is unimportant, but it is a good habit to order them in this way to make it easier to read the HTML if there are problems.

Note that not all tags, for instance the
tag used to define a line-break, require a closing tag.
