Styling GTK Buttons

[InKeaton]

Hi.
Sorry if this question may be somewhat unrelated, but i have a problem styling buttons which i cannot find an answer anywhere online

I made, for example, this simple widget:

config.js

import App from 'resource:///com/github/Aylur/ags/app.js';
import Widget from 'resource:///com/github/Aylur/ags/widget.js';

const myButton = () => Widget.Button({
    name: "button",
    className: "testbutton",
    label: "hi"
})

const Bar = ({ monitor } = {}) => Widget.Window({
    name: 'bar',
    anchor: ['top', 'left', 'right'],
    child: myButton(),
})

// exporting the config so ags can manage the windows
export default {
    style: App.configDir + '/style.css',
    windows: [
        Bar({ monitor: 0 }),
    ],
};

style.css

button {
  color: #E5EBE2;
  background-color: #9D4A2E; 
}

button :hover {
  background-color: aqua; 
}

this code should create an orange button, with teal text, that when hovered becomes aqua.
Instead, it follows my GTK theme settings, only the text seem to be affected

I just wanted to ask if some of you know about what may be the problem. Thanks in advance

button in css selects every button. There is probably another css selector which has priority.
you have added testbuttonas a classname, so you might want to use that in your css:

.testbutton {
  color: #E5EBE2;
  background-color: #9D4A2E; 
}

.testbutton:hover {
  background-color: aqua; 
}
