Question

What is the best way to apply CSS styles to different states in React?

I am endeavoring to adjust the size of an element by utilizing this code snippet.

const [size, setSize] = useState({});

The initial size I wish to set is:

transform: scale(1, 1) translate3d(0, 0, 0);

Upon clicking on the element, my aim is to enlarge it to the following dimensions:

transform: scale(2, 2) translate3d(0, 0, 0);

The method through which I will prompt the element to update to the new size is as follows.

const onClickHandler = (event) => {
setSize= transform: scale(2, 2) translate3d(0, 0, 0);
}

Answer №1

Here are two ways you can achieve the desired result:

Solution 1

const [style, setStyle] = useState({});

const onClickHandler = () => setStyle({
  transform: "scale(2, 2) translate3d(0, 0, 0)"
});

return (
  <div style={style}>
    {/* content goes here */}
  </div>
);

Solution 2

const [scale, setScale] = useState(1);
const style = useMemo(() => ({
  transform: `scale(${scale}, ${scale}) translate3d(0, 0, 0)`
}), [scale]);
const onClickHandler = () => setScale(2);


return (
  <div style={style}>
    {/* content goes here */}
  </div>
);
