Add disabled states for input[type='email'], input[type='text'], input[type='password']

[Laura Chan]

Hello 👋
Using 98.css in my own project at the moment and I would like to add disabled input[type="text"]. Basing it off this image I found, I think adding a silver background is enough. Something like

input[type='email']:disabled,
input[type='password']:disabled,
input[type='text']:disabled {
  background-color: var(--surface);
}
