CSS Border Properties
The CSS border properties allow you to specify the style and color of an element's border.
Border Style
The border-style property specifies what kind of border to display.
None of the border properties will have ANY effect unless the border-style property is set!

border-style values: none:
Defines no border dotted:
Defines a dotted border dashed:
Defines a dashed border solid:
Defines a solid border double:
Defines two borders. The width of the two borders are the same as the border-width value groove: Defines a 3D grooved border. The effect depends on the border-color value ridge:
Defines a 3D ridged border. The effect depends on the border-color value inset:
Defines a 3D inset border. The effect depends on the border-color value outset:
Defines a 3D outset border. The effect depends on the border-color value

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. Note: The "border-width" property does not work if it is used alone. Use the "border-style" property to set the borders first.

Example
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:
1. name - specify a color name, like "red"
2. RGB - specify a RGB value, like "rgb(255,0,0)"
3. Hex - specify a hex value, like "#ff0000"

You can also set the border color to "transparent".
 Note: The "border-color" property does not work if it is used alone.
Use the "border-style" property to set the borders first.

Example
 p.one {
border-style:solid;
border-color:red;
}
p.two {
 border-style:solid;
 border-color:#98bf21;
 }
