CSS outline-style Property


Set a style for the outline:

div {outline-style: dotted; }

Definition and Usage

An outline is a line that is drawn around elements (outside the borders) to make the element "stand out".

The outline-style property specifies the style of an outline.

Default value: none
Inherited: no
Animatable: no. Read about animatable
Version: CSS2
JavaScript syntax:"dashed"

Tips and Notes

An outline is a line around an element. It is displayed around the margin of the element. However, it is different from the border property.

The outline is not a part of the element's dimensions, therefore the element's width and height properties do not contain the width of the outline.

Browser Support

The numbers in the table specify the first browser version that fully supports the property.

outline-style 1.0 8.0 1.5 1.2 7.0
