[Plugin Meta Slider] – Font styling

Hi i found this link to styling it, but it doesnt seem to work.
I want the font size to be 12px and font-family:gerorgia.
Im using the flex slider and not nivo.

.metaslider .caption,
.metaslider .cs-title,
.metaslider .nivo-caption {
    font-size: 1.3em; /* adjust as necessary */
}
