HTML and CSS Reference
Elements are designators that define the structure and content of objects within a page.
Some of the more frequently used elements include multiple levels of headings (identified
as <h1> through <h6> elements) and paragraphs (identified as the <p> element); the list
goes on to include the <a> , <div> , <span> , <strong> , and <em> elements, and many
Elements are identified by the use of less-than and greater-than angle brackets, < > , sur-
rounding the element name. Thus, an element will look like the following:
The use of less-than and greater-than angle brackets surrounding an element creates what
is known as a tag . Tags most commonly occur in pairs of opening and closing tags.
An opening tag marks the beginning of an element. It consists of a less-than sign followed
by an element's name, and then ends with a greater-than sign; for example, <div> .
A closing tag marks the end of an element. It consists of a less-than sign followed by a
forward slash and the element's name, and then ends with a greater-than sign; for example,
The content that falls between the opening and closing tags is the content of that element.
An anchor link, for example, will have an opening tag of <a> and a closing tag of </a> .
What falls between these two tags will be the content of the anchor link.
So, anchor tags will look a bit like this:
1. <a> ... </a>
Attributes are properties used to provide additional information about an element. The most
common attributes include the id attribute, which identifies an element; the class attrib-

dable content; and the href attribute, which provides a hyperlink reference to a linked
Attributes are defined within the opening tag, after an element's name. Generally attributes
include a name and a value. The format for these attributes consists of the attribute name
followed by an equals sign and then a quoted attribute value. For example, an <a> element
including an href attribute would look like the following:
