Hello,
For your text customization, you have to find the class name and use it to modify your text, change color, font, size etc !
In order to find text or element class name, you can use your navigator inspector tool, point element and right click, and select inspect tool to have this :
Next see this
Css references
, and maybe especially
this one part
for text properties.
For make an example from my class example, you must use this kind of Css code :
.item-103.current.active {
color: red;
}
And so, text will be red.
Hope this will help you, now you have everything to be able to customize your display.
Regards
