CSS | flex Property

The flex property in CSS is the combination of flex-grow, flex-shrink, and flex-basis property. It is used to set the length of flexible items. The flex property is much responsive and mobile friendly. It is easy to positioning child elements and the main container. The margin doesn’t collapse with the content margins. Order of any element can be easily changed without editing the HTML section.

Syntax:

flex: flex-grow flex-shrink flex-basis|auto|initial|inherit;

Property Values:

  • flex-grow: A number that specify, how much items will grow relative to the rest of the flexible items.
  • flex-shrink: A number that specify, how much items will shrink relative to the rest of the flexible items.
  • flex-basis: It sets the length of items. Legal values of flex basis are: auto, inherit, or a number followed by %, em, px or any other length unit.
