Html style div height auto

CSS height Property

The height property is used to set an element’s height. This property does not include padding, borders, or margins. The height property can be specified by «px», «cm», «vh» or by percentages. The default value is «auto».

If the min-height and max-height properties are used, it will override the height property.

If height is set to one of the numeric values like (r)em, px or %, and if if the content doesn’t fit inside of the particular height, this will cause overflowing. The CSS overflow property specifies, how the container will deal with the overflowing.
