### Auto set font size For letter type Avatar, when the letters are too long to display, the font size can be automatically adjusted according to the width of the Avatar. ```jsx live () => { const UserList = ['A', 'Tom', 'Jack', 'Stuart', 'UUUUUUUU']; const colorList = ['#7265e6', '#f56a00', '#ffbf00', '#00a2ae', '#f56a00']; const [user, setUser] = React.useState(UserList[0]); const [color, setColor] = React.useState(colorList[0]); const changeUser = () => { const idx = UserList.indexOf(user); setUser(idx < UserList.length - 1 ? UserList[idx + 1] : UserList[0]); setColor(idx < colorList.length - 1 ? colorList[idx + 1] : colorList[0]); }; return (
{user}
); }; ```
