How to write hover effect

- If I want to apply hover effect then how I could I manage.
e.g.
firstRow: {
padding: '10px',
fontFamily: 'Lato',
},
I want to be apply hover on firstRow.

- And also If I want to override predefine classes then Is that possible with it?
e.g ( .ant-selection )

The issue names no source files or tests; start by reviewing the react-with-styles usage documentation and styling examples. Document how to apply a hover style to firstRow and how to override predefined classes such as .ant-selection, with examples that make the expected behavior clear.
