Specifies the style of the left, right, top, and bottom borders of the object.

CSS Backgrounds and Borders Module Level 3, Section 4.2

Syntax

border-style: none | hidden | dotted | dashed | solid | double | groove | ridge | inset | outset {1,4}

Property values

none: Initial value. Border is not drawn, regardless of any border-width.
hidden: Internet Explorer 8 and later. Same as none, except in terms of conflict resolution of collapsed borders. Any element with a hidden border suppresses all shared borders at that location. Borders with a style of none have the lowest priority.
dotted: Border is a dotted line.
dashed: Border is a dashed line.
solid: Border is a solid line.
double: Border is a double line drawn on top of the background of the object. The sum of the two single lines and the space between equals the border-width value. The border width must be at least 3 pixels wide to draw a double border.
groove: 3-D groove is drawn in colors based on the value.
ridge: 3-D ridge is drawn in colors based on the value.
inset: 3-D inset is drawn in colors based on the value.
outset: 3-D outset is drawn in colors based on the value.

Examples

The following example shows how to use border-style to apply different border styles on the same div element.

HTML


<div id="multiple">
   border-style: dotted dashed ridge double;
</div>

In the CSS below, border-style is set to dotted dashed ridge double. This sets the border-top-style to dotted, border-left-style to dashed, border-bottom-style to ridge, and border-right-style to double.
