Customize global styles in React using the `react-helmet` library with a `:root`

Is it possible to enhance global styles in React by adding a :root style block with CSS variables? I included the following code snippet in my layout.tsx file, but when I run it in Visual Studio 2022 React project, the page appears blank. However, if I replace the style block with a meta tag, the meta tag shows up on the page, indicating that react-helmet is functioning properly. Additionally, an error message "(ts) cannot find name --mainThemeF" pops up in Visual Studio when hovering over the style tag.

I'm unsure if the layout.tsx file is the appropriate location for implementing these global styles or if there's a different "Master" type page where this should be done. Could someone confirm if this method of adding global styles in React is correct, as I am relatively new to working with it. Thank you.

   <React.Fragment>
        <Helmet>
            <style type="text/css">
                :root {
                    --mainThemeF: #ffffff;
                    --mainThemeB: #006633;
                    etc...
                 {
             </style>
         </Helmet>

Answer №1

Resolved the issue, just like that. I found the solution in the documentation - why didn't I check there sooner?

<React.Fragment>
        <Helmet>
            <style type="text/css">{`
            :root {
                --mainThemeF: #ffffff;
                --mainThemeB: #006633;                    
             {
         `}</style>
     </Helmet>
