How to move text up using CSS when nothing is working

try a negative margin.

margin-top: -10px; /* as an example */

you can try

position: relative;
bottom: 20px;

but I don't see a problem on my browser (Google Chrome)

footerText {
    line-height: 20px;
}

you don't need to start playing with position or even layout of other elements... use this simple solution

used the following snippet and it worked fine..

.smallText .bmv-disclaimer {
   height: 40px;
}
