Open source ionic web app style sheet for desktop screens

Does anyone know an existing template (free or paid) or open source stylesheet for an ionic desktop web app or PWA? The default styles look pretty bad for a large screen web app. It’s a pretty large task to restyle everything and unfortunately, because of the unique component names, we can’t use any existing angular website templates. The templates that i have found that claim to be PWA’s look bad. Even an open source ionic app that is meant to be cross platform would be helpful. It would be great if the template had the logic to switch between mobile or desktop stylesheets and looked good in both.

As an example this template claims to be a PWA template but really looks like a zoomed in mobile app when you use it in the browser.

I am looking for templates or themes similar to :

But using ionic and with logic to switch styles to make the template look good across browsers.
