- flex-shrink:a number specifying how much will this item will shrink relative to the rest of the flexiable items.The default value is 1. (when the value of the flex-shrink is 0,the item will just appear as in it’s original width,but in order to fit to the container,the default value of the flex-shrink is 1 ,which means that these items will shrink by default.)
