CSS Border (Cont.)

Border Width
The border-width property is used to set the width of the border. The width is set in pixels, or by using one of the three pre-defined values: thin, medium, or thick. The border-width property does not work if it is used alone. Use the border-style property to set the borders first. 
   p.one { border-style:solid;  border-width:5px; }
   p.two { border-style:solid;  border-width:medium; }
Border Color
The border-color property is used to set the color of the border. The color can be set by name, RGB, or hex. You can also set the border color to transparent. The border-color property does not work if it is used alone. Use the border-style property to set the borders first. 
   p.one { border-style:solid;  border-color:red; }
   p.two { border-style:solid;  border-color:#98bf21; }
Border—Shorthand Property
As you can see from the examples above, there are many properties to consider when dealing with borders. To shorten the code, it is also possible to specify all the border properties in one property. This is called a shorthand property. The shorthand property for the border properties is border: 
   border:5px solid red;
When using the border property, the order of the values are: It does not matter if one of the values above are missing (although, border-style is required), as long as the rest are in the specified order.
