SCSS for form input box

Hi All

I am new to creator.

I have started working on a small project for an app using Creator.

I would like to change the color of the text used in put text box. But using the following does not make any difference
color: white !important;

As it does not toggle switch and scroll bards components.

Can someone advice me on how i can get more information on all the components and what parameters can be changed?

Thank You
