flex-grow

Flex growth

The flex growth determines if or how much a flex item grows in a flexbox container when there is extra space.

If set to 0, an element won’t grow at all, if set to any value above that, it will. If there are multiple elements with a positive grow value in a flexbox container, the flex-grow value acts as a weight. For example, if all elements have growth value of 1, they all grow an equal amount, if one has a growth value of 2, it will grow more than the others.
