137. What does`flex:1` mean?

flex:1 is a shorthand property that sets the flex-grow, flex-shrink, and flex-basis properties all at once.

flex-grow determines how much the item will grow relative to the rest of the flexible items inside the same container when there is extra space.

flex-shrink determines how the item will shrink relative to the rest of the flexible items inside the same container when there is not enough space.

flex-basis sets the initial main size of the flex item before any free space is distributed, and specifies the default size of the item.

So, when we set flex:1, it means that the item will grow and shrink equally with the other items in the container, and its initial size will be determined by the available space in the container.
