CSS Margin and Padding
What are CSS Margin and Padding?
CSS Margin and Padding are spacing properties used to control the space around and inside HTML elements. Margin creates space outside an element, while Padding creates space between the element’s content and its border. Both properties are important for creating clean, readable, and professional website layouts.
Difference Between Margin and Padding
Why Use Margin and Padding?
Margin and Padding help arrange elements properly on a webpage. They are commonly used for creating card layouts, buttons, navigation menus, forms, sections, and responsive designs. Without proper spacing, webpage elements can look crowded and difficult to read.

.card{
width:250px;
border:2px solid #007BFF;
