Constituent properties

This property is a shorthand for the following CSS properties:

• border-bottom-style
• border-left-style
• border-right-style
• border-top-style

Syntax

/* Keyword values */ border-style: none; border-style: hidden; border-style: dotted; border-style: dashed; border-style: solid; border-style: double; border-style: groove; border-style: ridge; border-style: inset; border-style: outset; /* top and bottom | left and right */ border-style: dotted solid; /* top | left and right | bottom */ border-style: hidden double dashed; /* top | right | bottom | left */ border-style: none solid dotted dashed; /* Global values */ border-style: inherit; border-style: initial; border-style: revert; border-style: revert-layer; border-style: unset; 

The border-style property may be specified using one, two, three, or four values.

• When one value is specified, it applies the same style to all four sides.
• When two values are specified, the first style applies to the top and bottom, the second to the left and right.
• When three values are specified, the first style applies to the top, the second to the left and right, the third to the bottom.
• When four values are specified, the styles apply to the top, right, bottom, and left in that order (clockwise).

Each value is a keyword chosen from the list below.

Values

<line-style>

Describes the style of the border. It can have the following values:

none

Like the hidden keyword, displays no border. Unless a background-image is set, the computed value of the same side's border-width will be 0, even if the specified value is something else. In the case of table cell and border collapsing, the none value has the lowest priority: if any other conflicting border is set, it will be displayed.

hidden

Like the none keyword, displays no border. Unless a background-image is set, the computed value of the same side's border-width will be 0, even if the specified value is something else. In the case of table cell and border collapsing, the hidden value has the highest priority: if any other conflicting border is set, it won't be displayed.

dotted

Displays a series of rounded dots. The spacing of the dots is not defined by the specification and is implementation-specific. The radius of the dots is half the computed value of the same side's border-width.

dashed

Displays a series of short square-ended dashes or line segments. The exact size and length of the segments are not defined by the specification and are implementation-specific.

solid

Displays a single, straight, solid line.

double

Displays two straight lines that add up to the pixel size defined by border-width.

groove

Displays a border with a carved appearance. It is the opposite of ridge.

ridge

Displays a border with an extruded appearance. It is the opposite of groove.

inset

Displays a border that makes the element appear embedded. It is the opposite of outset. When applied to a table cell with border-collapse set to collapsed, this value behaves like ridge.

outset

Displays a border that makes the element appear embossed. It is the opposite of inset. When applied to a table cell with border-collapse set to collapsed, this value behaves like groove.
