Text in a flex container doesn't wrap in IE11

Answer 1

Hi for me I had to apply the 100% width to its grandparent element. Not its child element(s).

.grandparent {
    float:left;
    clear: both;
    width:100%; //fix for IE11 text overflow
}

.parent {
    display: flex;
    border: 1px solid red;
    align-items: center;
}

.child {
    border: 1px solid blue;
}
