Word-wrap on Text

Hi Folks,

How can I wrap text on <P> element and make it occupy the full size of a container which has CSS style

    -webkit-box-flex: 1;
    -moz-box-flex: 1;
    -webkit-flex: 1 0 auto;
    -ms-flex: 1 0 auto;
    flex: 1 0 auto;
    -webkit-align-self: stretch;
    -ms-flex-item-align: stretch;
     align-self: stretch;

The word wrap doesn’t work when it’s inside a Flex container?

Thanks in advance.
