Hi,

To change the font size of slider title and description
Go to Appearance -> Theme Options -> Basic Settings -> Slider Caption Colors -> Select font size for slider title

To move the slider text lower and display it in full width
Go to Appearance -> Editor -> style.css -> add below css code at the end of file

.nivo-caption { width:80% !important; bottom:20% !important; }
