Style flex Property

❮ Style Object

Example

Let all the flexible items be the same length, regardless of its content:

for (i = 0; i < y.length; i++) {
  y[i].style.flex = "1";
}
Try it Yourself »

Definition and Usage

The flex property sets or returns the length of the item, relative to the rest of the flexible items inside the same container.

The flex property is a shorthand for the flexGrow, flexShrink, and the flexBasis properties.

Note: If the element is not a flexible item, the flex property has no effect.
