The flex-grow property specifies how much the item will grow compared to other items inside that container. In other words, it is the ability of an item to grow compared to other items present inside the same container.

Note: If the item in the container is not a flexible item then the flex-grow property will not affect that item.


flex-grow: number| initial| inherit;

Default Value: 0

Property values:  

  • number: A number that defines how the item will grow compare to other flexible items.
  • initial: It sets the value to it’s default value.
  • inherit: It inherit the property from it’s parent elements.

Example: Here we are going to see in a single container there are 5 divs, we will apply the flex-grow: On 2nd div and that div will grow compare to other 4 divs. We can apply flex-grow on any document in the same container that div will grow compared to other div’s width, the flex-grow property will help that div to grow in comparison to other items in that container.
