how can i change font size in Label ???

Vaadin 6 / 7 / 8 Framework UI

I’m also trying to change the font size of a lable … without success.

I have defined following css rule:

/** title font */
.v-label-dfFontTitle {
  text-align: center;
  vertical-align: middle;
  font-size: 150%;
/*  font-weight: bold; */
  padding-bottom: 5px;
  border: blue solid 1px;
}

And on Java side I use following label:

    Label lblTitle = new Label(Lng.get(I18N_LBL_TITLE_P2, loginCtlr.getCompanyName(), loginCtlr.getShortProjectName()));
    lblTitle.addStyleName(CSSStyleNames.dfFontTitle.name());
    layoutTitle.addComponent(lblTitle, 0, 0);
    layoutTitle.setComponentAlignment(lblTitle, Alignment.MIDDLE_CENTER);

If I run the application the blue frame is shown like it is was defined in CSS. So my defined CSS rule will be taken. But the font size is not bigger as normal font size. Also If I look in the CSS rules on browser side (via WebDeveloper) the font-size rule is shown (150%) and I cannot find any reason why the font has normal size.

Any tips?

Thanks,
Steffen
