HTML uses tags that are encased in brackets. HTML documents consist of elements which are constructed with tags. For instance, a paragraph is considered to be an html element constructed with the tags <P> and </P>. The <P> tag begins the paragraph element and the </P> tag ends the element. Not all tags have a tag for ending the element such as the line break, <br> tag. The HTML document is begun with the <html> tag and ended with the </html> tag. Elements of an HTML document include the HEAD, BODY, paragraphs, lists, tables, and more. Elements may be embedded within each other. Also some elements have attributes embedded in the tag that define characteristics of the element such as the placing of text, size of text, source of an image, and other characteristics depending on the element.
