Tag (HTML)
From Wiki @ Karl Jones dot com
In HTML, tags represent HTML elements.
An HTML element is abstract. A tag implements an HTML element in a web page or other document.
One Tag, Two Tag
Some elements have one tag:
<img src="image.jpg" alt="element with one tag" />
Most elements use two tags: an opening tag, and a closing tag:
<p>Text inside paragraph.</p>
Elements with two tags serve as containers. Any content between the opening tag and the closing tag is contained by the container element.
