CSS border sets the width, style, and color of an element's border. You can apply one value to all sides with border: 2px solid #3b82f6; or target individual sides with border-top, border-right, border-bottom, border-left. For advanced effects (e.g. gradient or glow), box-shadow or border-image are often used.
