Is there a way to make the tooltip arrow bigger in Material UI v4? I came across a workaround for the react-tooltip library that involves using the border-width css property. Any suggestions for achieving a similar result with MUI tooltips?

To adjust the size of the arrow using CSS, you can utilize the fontSize property. Here's an example:
"& .MuiTooltip-arrow": { fontSize: "large"}To customize the appearance, you must override two style classes.
When you override the popperArrow class, the styles will be applied to the Popper component if arrow={true}. If you override the arrow class, the styles will be applied to the arrow element when overriding the arrow class.
const useStyles = makeStyles({
popperArrow: arrowGenerator(),
arrow: {
width: 24,
height: 17, /* = width / sqrt(2) = (length of the hypotenuse) */,
}
});
export default function ArrowTooltips() {
const classes = useStyles();
return (
<Tooltip title="Add" arrow classes={classes}>
<Button>Arrow</Button>
</Tooltip>
);
}
The arrowGenerator function is defined to apply different styles depending on the placement of the Tooltip.
function arrowGenerator() {
return {
'&[x-placement*="bottom"] $arrow': {
marginTop: -17
},
'&[x-placement*="top"] $arrow': {
marginBottom: "-0.71em"
},
'&[x-placement*="right"] $arrow': {
marginLeft: "-0.71em"
},
'&[x-placement*="left"] $arrow': {
marginRight: "-0.71em"
}
};
}
To achieve the best outcome, make sure to adjust the margin values in the arrowGenerator function based on the width and height values set for the arrow class.
For instance, if you set the placement="bottom" prop on your component, in the
'&[x-placement*="bottom"] $arrow':marginTop to the negative value of the height set for your arrow.
