Hello everyone,

I state that I know well the operation of the style sheets, but are some days that I try to understand how the two style sheets work .css dark and light on the UI of QGroundControl … Honestly I did not understand their influence on the themes of the software. …
Kindly can someone tell me well how they work?

Thank you!!!

In reality these are used very little in QGC now since they work on QWidgets ui. 99% of QGC ui has moved to Qml.

Ok !!
So confirm that the two .css files (style-dark and style-light) in the QGC project no have influence on the UI?

Thank you for your answer…
