The border-style CSS property is a shorthand property that sets the line style for all four sides of an element's border.

Syntax

/* Keyword values */
border-top-style: none;
border-top-style: hidden;
border-top-style: dotted;
border-top-style: dashed;
border-top-style: solid;
border-top-style: double;
border-top-style: groove;
border-top-style: ridge;
border-top-style: inset;
border-top-style: outset;

/* vertical | horizontal */
border-style: dotted solid;

/* top | horizontal | 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: 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

<br-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 calculated value of border-top-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 calculated value of border-top-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 calculated border-top-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 or border-top-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 groove.
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 ridge.

Formal syntax

<line-style>{1,4}

where
<line-style> = none | hidden | dotted | dashed | solid | double | groove | ridge | inset | outset
