CSS outline Property

Description

The outline CSS property is used to style the outline that appears around an element when it is focused or active, typically due to user interaction, such as clicking with a mouse or tabbing through form fields. It allows web developers to customize the appearance of this outline, including its color, style, and width. The outline property is often used in conjunction with the :focus pseudo-class to enhance accessibility and usability by making interactive elements more visually distinct when they receive keyboard or mouse focus, ensuring a better user experience for those with disabilities or using assistive technologies. Individual properties are: outline-style, outline-width and outline-color.
