Description

The shape-margin CSS property is used to control the amount of space between the content of a non-rectangular CSS shape and the outer boundary of that shape. This property is particularly useful when working with CSS shapes created using properties like shape-outside or clip-path. By adjusting the shape-margin, web developers can fine-tune the positioning of text and other content around these non-standard shapes, ensuring proper spacing and alignment within the layout of a web page. It allows for more precise control over the flow of content around complex shapes, improving the overall design and readability of web content.
