Border shorthand is the most extended shorthand for a single property. You have several shorthand options.
Each category of shorthand has corresponding shorthand, as follows:
border-right, border-left, border-top, border-bottom border-width border-style border-color
So, you can write this:
border-right: 1px dotted red;
The property then causes the selected element to have a right border of 1 pixel, dotted, and of the color red.
border Property
This shorthand property sets the width, style, and color for all four sides of the element in question:
border: thick ridge white;
In Figure 11-7, you can see the results for this.
