Code Walkthrough and Explanation


flex-shrink

In CSS, the flex-shrink property is used in conjunction with the flex-grow property to determine how flex items are resized when there is not enough space available in the flex container.

The flex-shrink` property controls the ability of a flex item to shrink when the available space in the flex container is less than the total size of all the flex items. It is a unitless value that represents the proportion of the available space that the flex item should take up when there is not enough space.

A value of 0 means that the flex item will not shrink, while a value greater than 0 means that the flex item will shrink proportionally to its flex-shrink value. The default value of flex-shrink is 1, which means that all flex items will shrink proportionally by default. A value of flex-shrink: 0 will prevent a flex item from shrinking.
