CSS Border

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.

Note: 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 per-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:

• name - specify a color name, like "red"
• RGB - specify a RGB value, like "rgb(255,0,0)"
• 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;
}

Border - Individual sides

In CSS it is possible to specify different borders for different sides:

Example

p {
    border-top-style: dotted;
    border-right-style: solid;
    border-bottom-style: dotted;
    border-left-style: solid;
}

The example above can also be set with a single property:

Example

border-style: dotted solid;

The border-style property can have from one to four values.

• border-style: dotted solid double dashed;
• top border is dotted
• right border is solid
• bottom border is double
• left border is dashed

• border-style: dotted solid double;
• top border is dotted
• right and left borders are solid
• bottom border is double

• border-style: dotted solid;
• top and bottom borders are dotted
• right and left borders are solid

• border-style: dotted;
• all four borders are dotted

The border-style property is used in the example above. However, it also works with border-width and border-color.

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 individual border properties in one property. This is called a shorthand property.
The border property is a shorthand for the following individual border properties:

• border-width
• border-style (required)
• border-color

Example

border: 5px solid red;
