What is a CSS border?

A CSS border is a visual outline around HTML elements that can be styled with different widths, colors, patterns, and sides. Borders help define element boundaries, create visual separation, and add decorative effects to web designs. The border property supports multiple styles including dotted, dashed, solid, double, and more, allowing designers to create diverse visual effects.
