Last Updated : 31 Jul, 2019

The HTML DOM style flexGrow property is used as a measure to determine how much an item will grow relative to the rest of the flexible items inside the same container.

Syntax:

Return flexGrow property:
```
object.style.flexGrow
```

Set flexGrow property:

object.style.flexGrow = "number|initial|inherit"

Properties:

number: It specifies the quantity in number which determines how much the item will grow relative to the rest of the flexible items.
initial: It sets the flexGrow property to its default value.
inherit: It inherits the property values from its parent element.

Return Value:
It returns a string, representing the flex-grow property of the element.

Example-1: Item grow relative to the rest of the flexible items inside the same container.
