You have decided that you will design a title so that it looks good in any screen resolution from 640x480 to 1024x768. You want the heading to be dramatic, which you have decided means as big as possible without it breaking into two lines on a small screen. The title is “Typography is Fun!” Create a Web page with several versions of the title, each using a different typeface. Use at least different three different typefaces. For each version, specify the typeface and size for the font. Note: there is no unique “correct” answer. Restrict yourself to the typefaces described in this chapter.
The design specifications said that the title shouldn’t break into two lines when seen on a 640x480 monitor, so the first thing to do is to determine the minimum width. For the following example, the width is 540 pixels, but it’s okay if the width is a little wider. The main thrust is to create titles that all have the same width, and the point of the exercise is that fonts having different typefaces but identical point size will take up varying horizontal space due to the face that a point size specifies a vertical measure, not a horizontal one.
