}
#hp-ctn-howItWorks {
    padding:0px 0px 0px 0px;
    text-align: center;
    margin:0px;

    border-radius: 5px 5px 0px 0px;
    -moz-transform:rotate(-90deg);
    -ms-transform:rotate(-90deg);
    -o-transform:rotate(-90deg);
    -webkit-transform:rotate(-90deg);
    transform-origin: bottom right;
    position: fixed;
    right: 0px;
}
#hp-ctn-howItWorks p {
    color:#fff;
    display:inline-block;
    line-height:40px;
}

You can do this by using the html non breaking space   here <p>Como&nbsp;funciona</p>

this is how it looks after changing it and the margin on the image
