CSS Borders

Borders frame elements with style, width and colour on each side. They add structure and visual weight to cards and buttons.


CSS Borders

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).

Example

p.dotted {border-style: dotted;}
p.dashed
{border-style: dashed;}
p.solid {border-style: solid;}
p.double
{border-style: double;}
p.groove {border-style: groove;}
p.ridge
{border-style: ridge;}
p.inset {border-style: inset;}
p.outset
{border-style: outset;}
p.none {border-style: none;}
p.hidden {border-style: hidden;}

p.mix {border-style: dotted dashed solid double;}

Note: None of the OTHER CSS border properties (which you will learn more about in the next chapters) will have ANY effect unless the border-style property is set!
