What is the meaning of `auto` value in a CSS property.

css

Solution

The value of said property is adjusted automatically according to the content or the context of the element.

For example, a block-level element with `height: auto` will grow taller as it contains more text. For another example, a block element with `margin: 0 auto` will have the left and right margins increased until it becomes centered along the y-axis of the viewport.

It really depends on the property you give the value to, different properties behave differently depending on the content and context.
