Aqui está um exemplo demonstrando a keyframes
sintaxe dentro de makeStyles
:
import React from "react";
import ReactDOM from "react-dom";
import { makeStyles } from "@material-ui/core/styles";
import Button from "@material-ui/core/Button";
import clsx from "clsx";
const useStyles = makeStyles(theme => ({
animatedItem: {
animation: `$myEffect 3000ms ${theme.transitions.easing.easeInOut}`
},
animatedItemExiting: {
animation: `$myEffectExit 3000ms ${theme.transitions.easing.easeInOut}`,
opacity: 0,
transform: "translateY(-200%)"
},
"@keyframes myEffect": {
"0%": {
opacity: 0,
transform: "translateY(-200%)"
},
"100%": {
opacity: 1,
transform: "translateY(0)"
}
},
"@keyframes myEffectExit": {
"0%": {
opacity: 1,
transform: "translateY(0)"
},
"100%": {
opacity: 0,
transform: "translateY(-200%)"
}
}
}));
function App() {
const classes = useStyles();
const [exit, setExit] = React.useState(false);
return (
<>
<div
className={clsx(classes.animatedItem, {
[classes.animatedItemExiting]: exit
})}
>
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<Button onClick={() => setExit(true)}>Click to exit</Button>
</div>
{exit && <Button onClick={() => setExit(false)}>Click to enter</Button>}
</>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
