Vertically center a button

[tjflamezz]

I realize this post is a bit old, but I was just looking at this and in order to keep the items stretched to be with a 100% width. Here is an alternative:

.center-content > *  {
    -webkit-box-ordinal-group: 1;
    -moz-box-ordinal-group: 1;
    -webkit-order: 0;
    -ms-flex-order: 0;
    order: 0;
    -webkit-box-flex: 0;
    -moz-box-flex: 0;
    -webkit-flex: 0 1 auto;
    -ms-flex: 0 1 auto;
    flex: 0 1 auto;
    -webkit-align-self: stretch;
    -ms-flex-item-align: stretch;
    align-self: stretch;
    }

So the lines being changed are:

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