Css to improve look and feel of data grid

Hi, I want to use custom css to improve look of data grid. I need to change data grid header background color and font color, also hover and selection color on data grid rows. I tried to use style in Properties->Appearance->Style in datagrid but I can not achieve my look. How can I create custom class to achieve these changes?
