Are max-width:auto and max-width:100% the same thing?

Does

max-width set to auto

have the same result as setting

max-width to 100%

If not, what is the distinction between them?

Answer №1

There is a distinction between the values of auto and none when it comes to defining the maximum width of an element.

While auto is invalid for max-width, none signifies that there is no defined upper limit for the width of the element as per the specification outlined in max-width.

It's important to note that although none is not equivalent to 100%, setting a value of 100% means that the element can only expand up to the width specified by its containing block, as detailed in the width property with percentage widths.

By using none, you run the risk of extending the element beyond the confines of its container block, leading to overflow scenarios such as setting width: 150%. However, a max width restriction of 100% would override this 150% setting and enforce the specified limit.
