Automatically Calculating Margin

What happens when you assign the "auto" value to a margin?

The auto value means 'automatically calculate the margin.'

For example, setting margin: auto; will automatically calculate and set equal margins on the left and right sides of an element, effectively centering the element. margin: auto; is commonly used in CSS for centering elements.

Note that you cannot assign the auto value to padding. In other words, padding: auto; is not valid CSS.

Padding deals with internal spacing within an element, which is typically determined by the size or content of the element.
