How to theming react components with css variables?


Asked by Bryan Phillips on Dec 15, 2021 CSS



That could be either theming through higher-order components, passing themes as props (usually with the help of React.Context) or using popular libraries like styled-components. Today, thanks to ‘CSS custom properties’, a.k.a ‘CSS variables’, we shift the weight towards plain CSS.
Similarly,
Two ways to theme React components using CSS custom properties. The css-variable is the name of the CSS variable and value is its — you guessed it — value. To define a CSS variable we append the double -- followed by the variable name. Here, we set the main color of our app to be “orangered”.
Likewise, CSS variables are really cool. You can use them for a lot of things, like applying themes in your application with ease. In this tutorial I'll show you how to integrate them with React to create a ThemeComponent (with context!).
Indeed,
Stored properties: CSS variables that are not used directly to style components but are used to store sets of values. Theme: A set of stored properties, representing a particular styling. We set the ‘selected properties’ to a theme (a set of ‘stored properties’). This will serve as our default theme.

Final React class component should look like this: 2. React Hooks approach This is very similar to a Class component. For the Hooks approach, let’s create a function, and name it ButtonHooksComponent. This function will return the known markup. Assuming you’ve already imported useState hook, we’ll add a default state.
