Practical application instructions

Minimum width (min-width) and maximum width (max -width) is used to set the minimum and maximum width restrictions of the image. For example, when a picture is used as the main list and the size of the picture in the object is variable, in order to avoid making it too small and inconsistent, we can use the CSS minimum width style. For another example, when there are articles and pictures mixed in a box, sometimes the width of the picture cannot be determined. At this time, if the width of the html img picture exceeds the width of the p box, the picture may burst the p box and cause confusion.
