The CSS border properties allow you to specify the style, size, and color of an element's border.
The border-style property specifies what kind of border to display.
 |
Note: None of the border properties will have ANY effect unless the border-style property is set! |
|---|
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
Try it yourself: Set the style of the border
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.
The border-color property is used to set the color of the border. The color can be set by:
You can also set the border color to "transparent".
If the border color is not set it is inherited from the color property of the element.
Note: The "border-color" property does not work if it is used alone. Use the "border-style" property to set the borders first.
In CSS it is possible to specify different borders for different sides:
The example above can also be set with a single property:
The border-style property can have from one to four values.
The border-style property is used in the example above. However, it also works with border-width and border-color.
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 individual border properties in one property. This is called a shorthand property.
The border property is a shorthand for the following individual border properties:
All the top border properties in one declaration
This example demonstrates a shorthand property for setting all of the properties for the top border in one declaration.
Set the style of the bottom border
