What is auto? It is used for many things such as flex and width ect…


#2

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.
