记录下Material-UI自定义样式，后面继续更新自定义样式，伪类选择器样式定义constuseStyles=makeStyles((theme)=>({paper:{marginTop:theme.spacing(8)、display:'flex',flexDirection:'column',alignItems:'center',},avatar:{margin:theme.spacing(2),backgroundColor:theme.palette.success.light,},form:{width:'100%',marginTop:theme.spacing(1),},submit:{margin:theme.spacing(1,0,2),backgroundColor:theme.palette.success.light,'&:hover':{backgroundColor:theme.palette.success.main,}},containerItem:{fontSize:'14px',textAlign:'right',color:'#737373','&:hover':{color:theme.palette.success.light,}}}))其他伪类同理
