5.4.1. Fonts with Style

font-style is very simple: it's used to select between normal text, italic text, and oblique text. That's it! The only complications are in recognizing the difference between italic and oblique text and knowing why browsers

By contrast, if you set only a style, you will still get a border. For example, let's say you simply want a border style of dashed for the top of an element and are willing to let the width default to medium and the color to be inherited from the element itself. All you need in such a case is the following:

P.roof {border-top: dashed;}

Another thing to note is that since each of these "border-side" properties applies only to a specific side, overrun either the right or left inner edge in its best attempt to display itself correctly, depending on which way it was floated. In such a case, you get the result shown in Figure 7-72.

Figure 7-72. Floating an image wider than its parent element

Here, a left-floated image is wider than its parent, so its right edge overruns the right edge of the parent element. Had the image been floated to the right, then it would have overrun the left side of the parent element instead.
