CSS outline-color property
- previous page outline
- Next Page outline-offset
Definition and Usage
Outline (outline) is a line drawn around an element, located outside the edge of the border, and can highlight the element. The outline property can set the outline line around an element.
Note:Always declare the outline-style property before the outline-color property. An element must have an outline before its color can be changed.
Note:Outline lines do not take up space and are not necessarily rectangular.
The outline-color property sets the color of the visible part of the entire outline of an element. Remember that the outline style cannot be none, otherwise the outline will not appear.
