CSS Borders
Last updated on
The border property allows you to specify how the border of the box representing an element should look. The border module consists of the following properties, border-color, border-style and border-width. In this post we will look at all three properties and how we can combined them into the shorthand property.
Border Style
The border-style property controls the type of border to display.
There is plenty of choice:
- dotted – A dotted border
- solid – A solid border
- dashed – A dashed border
- double – A double border
- groove – A 3D grooved border
- ridge – A 3D ridged border
- inset – A 3D inset border
- outset – A 3D outset border
- none – Default property, no border
- hidden – A hidden border

Border Width
The border-width CSS property controls the width of the four borders. In order to see the thickness of a border you must first specify the border-style property.
There is three pre-defined values which are:
- Thin
- Medium
- Thick
Alternatively you can set your own borders in px, pt, cm, em or any other value. You can also set different size borders for the 4 sides.

Border Color
The border-color property is used to set the color of the four borders. You can set the color using rgb(a), hex or name.
Borders Shorthand Property
You can combine the border-width, border-style and border-color into one property which is border.
