I think you dint get me. I’m not telling about deleting the parent theme css.
You said I have coped double time css in child theme style.css ( @import url(….) and the whole of style.css from parent theme). So I asked you how can I delete the copied parent css part in child theme style.css.
Hope am clear.

Another thing is, how can I make changes in child style.css if I do not have the complete code. (I understand the child theme style.css contains just few lines of child name, template name etc)
