I have a LCDUI List Screen Contains Title and Image from Rss File


I have one Detail Form n which i am able to display publish date and one hyperlink form Rss File

m_itemForm.append(new StringItem("Pub Date:",videoItem.getPubDate()));
final String URL = videoItem.getLink();
stringItem = new StringItem("Link: ", "Set", Item.HYPERLINK);

Now i want to decrease the font of a text on both the Screens(List and Form)?
