Ans:
- Outlines do not take up space, because they are always placed on top of the box of the element which may cause them to overlap other elements on the page.
- Unlike border-style, outlines won’t allow us to set each edge to a different width, or set different colors and styles for each edge. The outline is the same on all sides.
- Outlines do not have any impact on surrounding elements apart from overlapping.
- Unlike border-style, outlines do not change the size or position of the element.
- The CSS border properties allow you to specify the style and color of an element’s border. An outline is a line that is drawn around elements (outside the borders) to make the elements.
