CSS outline Property


Set the outline around a <p> 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.

Note: 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.

Default value: invert none medium
Inherited: no
Animatable: yes, see individual properties. Read about animatable Try it
Version: CSS2
JavaScript syntax:"#0000FF dotted 5px" Try it
