What is the effect of the margin property in CSS?

The margin property in CSS is designed to create space outside of an element. This space is crucial for setting the positioning of elements in relation to one another, allowing for better layout control and avoiding elements being cramped together. When you apply a margin to an element, it pushes other elements away from its boundaries, thereby increasing the separation between them.

This is particularly useful for creating a structured and visually appealing design, as it helps define the relationships between different components on a web page. The margin can take specific values for each side of an element (top, right, bottom, left) or use shorthand to apply the same value uniformly or different values simultaneously. Understanding how margins work is fundamental to effectively managing layout and spacing in web design.
