The basic element of the Web is a page. HTML tags that govern the appearance of a page are called attributes.
Attributes are parameters that help explain what function the tag or command is to perform.
One of the simplest attributes is to bold text. A more powerful tag is the image tag, which specifies the name of the image to insert within a page. Some attributes supply preferences about the appearance of a specific page element. For example, a table has attributes that describe its border width and the padding or space between cells. Keep in mind not all browsers display HTML the same way when you design your survey.
