The CSS border properties allow you to specify the style, width, and color of an element's border.
I have borders on all sides.
I have a red, bottom border.
I have rounded borders.
I have a blue, left border.
CSS Border Style
The border-style property specifies what kind of border to display.
The following values are allowed
- dotted - Defines a dotted border
- dashed - Defines a dashed border
- solid - Defines a solid border
- double - Defines a double border
- 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
- none - Defines no border
- hidden - Defines a hidden border
The border-style property can have from one to four values (for the top border, right border, bottom border, and the left border).
