How can I access CSS variables in a React component?

You can access CSS variables in a React component using the getComputedStyle method or by directly referencing them in your styles.

Can you show me an example of using getComputedStyle?

Sure! You can use it like this:

const element = document.getElementById('myElement');
const styles = getComputedStyle(element);
const myVar = styles.getPropertyValue('--my-variable');

This retrieves the value of the CSS variable --my-variable.

What if I want to change the CSS variable dynamically?

You can change a CSS variable dynamically by using the style property of an element. For example:

document.documentElement.style.setProperty('--my-variable', 'newValue');

Is there a way to use CSS variables with styled-components?

Yes! You can use CSS variables in styled-components by defining them in your global styles or directly in your component styles.
