Not directly the answer to your question, but if I may comment on the background to your question:

- There's a place for backend focused development for the web. So you don't have to be an expert in frontend. But it helps to understand frontend concerns so you can speak a frontend dev's language to build interfaces that work for their needs. Be it server-side or APIs.

- there are fun technicalities of frontend - state management, asynchrony, software architecture for these problem spaces - lots of things that turn out to be technically interesting where you might be able to carve out a niche for yourself so you don't have to spend most of your time pushing pixels

- like desktop and probably mobile app development has gui frameworks where you can assemble UIs with components with largely existing styling that just needs configuration, the web frontend space has component libraries with style plugins like bootstrap and material ui, where a lot of styling is done for you, and you can focus on assembling the application rather than visual design or pixel pushing. It's not perfect for all cases, but it's effective for many. Which means if you don't want to be designing and building websites, you can still build good looking applications for the web and focus most of your time on functionality.
