CSS Borders

Written by Michael Gearon on the

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.

Using the Shorthand Property

You can combine the border-width, border-style and border-color into one property which is border.
