Definition and Usage
The max-width property defines the maximum width of an element.
If the content is larger than the maximum width, it will automatically change the height of the element.
If the content is smaller than the maximum width, the
max-width property
has no effect.
Note: This prevents the value of the
width property from becoming larger than
max-width. The value of the
max-width property overrides
the width property.
