yes. i want to make the text bigger so they can see it better.
On the layout that you have your textbox - Add these events/actions:
(event) System - Start of layout > (action) Textbox > set css style to (property name) "font-size" (value) "xxem"
The xx is whatever size you want - i'd start small, maybe around 1.5.
The em is the postfix if you will.
Just keep editng the size (xx) till you find the right size, and you need to test it on different devices. It will be larger or smaller.
Also, click on the textbox object. In the properties window you will see "Auto font size" put this to no.
