Ulitmate styling possibilities of Fabric React components?

my.module.scss

@import '~office-ui-fabric-react/dist/sass/References.scss';

.myWebPartClass {
    //Key is using this format....  and reference this page for more details
    //https://www.w3.org/TR/CSS21/selector.html%23id-selectors#type-selectors
    //Basically, this will get any child elements of className={ styles.listViewTransparent }
    //Then find only items where the property data-automationid = DetailsRowFields.
    //You can use this syntax and others to filter on any element property, wildcard etc....
    
    .listViewTransparent *[data-automationid="DetailsRowFields"] {
          background-color:  #eaeaea ;
          transition: all 0.3s ease;
      }

  .listViewTransparent *[data-automationid="DetailsRowFields"] :hover  {
        background-color:  #c2c2c2 ;
        color: #212121;
        transition: all 0.3s ease;
    }
  
}

myElement.tsx

export function xyz(){
  
let listView = 
    <div 
      className={ styles.listViewTransparent }>
      <ListView
        items={theseAreItems}
        viewFields={viewFields}        
      />
    </div>;
