CSS outline Property

CSS Reference Complete CSS Reference

Example

Set the outline around an element:

p
{
outline:#00FF00 dotted thick;
}

Try it yourself »

Definition and Usage

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

The outline shorthand property sets all the outline properties in one declaration.

The properties that can be set, are (in order): outline-color, outline-style, outline-width.

If one of the values above are missing, e.g. "outline:solid #ff0000;", the default value for the missing property will be inserted, if any.

Default value: invert none medium
Inherited: no
Version: CSS2
JavaScript syntax: object.style.outline="#0000FF dotted thin"

Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The outline property is supported in all major browsers.

Note: IE8 supports the outline property only if a !DOCTYPE is specified.

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.

Property Values

Value Description
outline-color Specifies the color of the outline
outline-style Specifies the style of the outline
outline-width Specifies the width of outline
inherit Specifies that the value of the outline property should be inherited from the parent element
