The standard Blazor template uses Bootstrap. Some themes replace the original bootstrap, but good ones add to it. Depending on which type you choose, you will either replace the existing bootstrap files with your theme files, or you will add the theme files
to the existing styles and scripts. If you are paying for a theme, they should provide instructions on how to install them. It makes no difference whether you are working with Blazor, PHP or standard HTML. It's just referencing script and style files in a
web app.
