The flex-grow Property

In simple terms, we use flex-grow property to specify how much flex-container child elements will grow relative to other child elements.

We define it in integer value and the default is 0. You can not add negative values.

If all elements have the same flex-grow, then all items will get the same share space.

Example

The flex-shrink Property

This property is the opposite version of flex-grow.

flex-shrink property specifies how much flex-container child elements will shrink relative to other child elements.

Same as flex-grow, we define it in integer value and the default is 0. You can not add negative values.

Example

The flex-basis Property

Using the flex-basis property, we can define the initial size of flex item. It will shrink and grow is there is a room available but initially the element will take the defined size.

Example

How to use flex-grow, flex-shrink, and flex-basis properties together?

We can use flex property. It’s a shorthand property for the flex-grow, flex-shrink, and flex-basis properties.

Example

The following example will make the first element 200px initial size. Twice 0 won’t allow it to grow or shrink. Pretty handy if we have to keep an element in fixed size but need a freedom to adjust the elements nearby.
