What are styled components?
Styled-components is a popular library for React and React Native that allows developers to use component-level styles in their applications with a modern twist on the CSS-in-JS approach. Rather than handling styles separately or inline, styled-components seamlessly integrate the styling with the component itself, making it an intrinsic part of the component definition.
One of the significant benefits of using styled-components is the ability to pass props directly to your styles. This dynamic styling capability means that the appearance of a component can be easily modified based on its props, leading to more reusable and adaptable components. For instance, a button’s color could change based on a `primary` prop without the need for multiple classes or conditional style definitions.
Another advantage is automatic critical CSS, where styled-components only inject the styles for components that are rendered on the page, ensuring optimal performance. Additionally, styles are scoped to the component, preventing unwanted global style leaks and clashes.
Theming is also a breeze with styled-components. The library provides a `ThemeProvider` wrapper, allowing developers to define a theme object with shared style values and access them in any styled component.
