Center sweetalert text with css

I'm trying to center text in my swal-box, but it wont work:

CSS3:

.swal-modal {
    text-align: center;
}

JavaScript:

swal("myTitle", "some text \n some more text \n even more text);

You can center the text with css in swal-modal

.swal-modal .swal-text {
    text-align: center;
}
