A font size describes the height of the tallest characters in a font in terms of points It takes 72 27 points to make an inch Web browsers tend to use 8 points as the size of their base fonts by default In HTML files, font size may be modified by the Web author by using HTML tags
It is preferable to keep font types relative rather than absolute, so that visitors can adjust the sizes in their browsers With the font tag, use <font size="-2"> or <font size="+1"> instead of <font size="1"> or <font size="4"> With CSS, use font-size: 80%; or font-size: larger; instead of font-size: 10pt; or font-size: 18px; For more information about font sizes, see http: //www useit com/alertbox/9707a html
