CSS Custom Properties optimization guide in Nested Components with Styled Components
I'm refactoring my project and I'm stuck on something that should probably be simple. I'm working with an scenario with CSS custom properties (variables) not behaving as expected in my React application using Styled Components. I have defined several CSS variables in a top-level component, but when I try to use them in nested components, they seem to revert to their initial values instead of inheriting the updated ones. Here's a simplified version of what I have: ```jsx // TopLevelComponent.jsx import styled from 'styled-components'; const Container = styled.div` --primary-color: #3498db; background-color: var(--primary-color); padding: 1rem; `; const NestedComponent = styled.div` color: var(--primary-color); `; const TopLevelComponent = () => ( <Container> <NestedComponent> This text should be the primary color </NestedComponent> </Container> ); export default TopLevelComponent; ``` The expectation is that the text inside `NestedComponent` should be blue, matching the background of `Container`. However, it appears as black instead. I’ve tried adding a fallback color directly in the `color` property, but that didn’t change the situation. Additionally, I checked the browser's developer tools, and I can confirm that the CSS variable is correctly defined in the `Container`, but it seems like `NestedComponent` is not picking it up. I've also ensured that the version of Styled Components I'm using is 5.3.0, which should support CSS variables. What am I missing? Is there a proper way to ensure that CSS variables defined in a parent component are accessible and usable in styled components nested within it? This is my first time working with Javascript 3.10. I appreciate any insights! I'm developing on Ubuntu 20.04 with Javascript. I'd be grateful for any help.
