Set the outline around an element:
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|
The outline property is supported in all major browsers.
Note: IE8 supports the outline property only if a !DOCTYPE is specified.
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.
|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|
