Border-Right

Shorthand to set the 3 properties:

element { border-right: Border-right-width Border-right-style Border-right-color ;}

This shorthand is equivalent to the following:

element {
  border-right-width: thin | medium | thick | length | inherit ;
  border-right-style: style ;
  border-right-color: color ;
}

Alternatively you can choose to inherit from a parent element: border-right: inherit ;

The Border-Style property must be set for the Border-Width or Border-Color properties to have any effect.

The default property values, any value that is not specified in the shorthand will be set to the default.

  border-right-width: medium;
  border-right-style: none;
  border-right-color: 0;

Examples

Set the right border of H1 to a 2px dashed green line:

h1 {border-right: 2px dashed green;}

Set a large right border on a 0px element to create a left pointing triangle:

.left-arr {
 width: 0px;
 height: 0px;
 border-bottom: 20px solid transparent;
 border-top: 20px solid transparent;
 border-right: 20px solid black;
}
