The text enclosed within a heading typically is rendered by the browser
uniquely, depending upon the display technology available to it. The
browser may choose to center, format in boldface, enlarge, italicize, un-
derline, or change the color of headings to make each stand out within
the document. And in order to thwart the most tedious writers, often
users themselves can alter how a browser renders the different headings.
Fortunately, in practice most browsers use a diminishing character point
size for the sequence of headers so that
<h1>
text is quite large and
<h6>
text is quite minuscule (see
Figure 4-3
, for example).
