Edit text node (Label)

Hi guys anyone know how make this "Label" become major?
The original size is very small for my aplication.


Use your browser dev tools and examine the element that surrounds your label. That will tell you the CSS selector you need to target with some custom CSS.

I format Label like this:

<font size="4"><b>Primary Text</b></font><br><font color=#8493A3><font size="2"><b>Secondary Text</b></font>

This, f.e., provides you with a two-liner with different text sizes and different colours.
