Answer 1

In your project folder add a basic CSS file mystylesheet.css. Mutli-language editors like Atom are best for this type of things. The syntax highlighting works properly if you keep it named a CSS file.

Then drop the dot; qt knows what you mean.

mystylesheet.css

QWidget {
    border: 20px solid black;
    border-radius: 10px;
    background-color: rgb(255, 255, 255);
}

anyQelement.setStyleSheet(open('mystylesheet.css').read())
