Custom CSS – Guide

Hi,

Do you have any guide on how to work with custom CSS. In this case I want the total to be all the way to the left (https://ibb.co/vBwNNzG). I have tried several CSS, like for example:

div.viwec-text-total { display: none !important; } or .viwec-text-total { display: none !important; }

But they don’t work.
