CSS border Property

Topic: CSS3 Properties Reference« Prev|Next »

Description

The border property sets the width, style, and color for all four sides of an element's border. It is a shorthand property for setting the individual border properties i.e. border-width, border-style, and border-color in a single declaration.

The following table summarizes the usages context and the version history of this property.

Default value: See individual properties
Applies to: All elements
Inherited: No
Animatable: Yes, See individual properties. See animatable properties.
Version: CSS 1, 2, 3

Syntax

The syntax of the property is given with:

border [ border-width border-style border-color ] | initial | inherit
 

Note:If any property listed above is missing or omitted, the default value for that property will be inserted, if any. See individual properties for details.

The example below shows the border property in action.

  • h1 {
  •     border: 5px solid #ff0000;
  • }
  • p {
  •     color: #00ff00;
  •     border: 5px solid;
  • }
 

Note:If border-color is missing or not specified (e.g. border: 5px solid;) the value of the element's color property will be used instead. But, in the case of border-style, skipping or omitting the value will cause no border to show at all, because the default value for border-style property is none.
