CSS flex-grow Property

Example

Let the second flex-item grow three times wider than the rest:

/* Safari 6.1+ */
div:nth-of-type(1) {-webkit-flex-grow: 1;}
div:nth-of-type(2) {-webkit-flex-grow: 3;}
div:nth-of-type(3) {-webkit-flex-grow: 1;}

/* Standard syntax */
div:nth-of-type(1) {flex-grow: 1;}
div:nth-of-type(2) {flex-grow: 3;}
div:nth-of-type(3) {flex-grow: 1;}
