CSS outline-style Property
The outline-style property in CSS is used to customize the appearance of an element's outline. An element's outline and border are similar but not the same. The outline does not take up any space and is drawn outside of an element's border. Furthermore, by default, the outline is drawn around all four sides of the element, and there is no way to change this.
