I'm trying to understand whether it's possible to obtain all of a website's code. I know browsers can show the frontend files, but I'm specifically wondering whether the backend code is accessible too and whether there's a legitimate way to retrieve it.

You can view or download frontend resources such as HTML, CSS, JavaScript, and images through the browser’s developer tools or view-source option. The backend is different: it runs on the server, so visitors normally only receive its output, not the server-side code.
The question needs a bit more context, because “all the code” could mean downloading the public frontend files or accessing a project’s private source. Browser inspection tools only reveal files sent to your browser; they cannot legitimately reveal protected server-side code.
If it’s your own website, use the project repository, hosting dashboard, or a server backup to retrieve the complete code. If it belongs to someone else, you should ask the developers for access. Trying to obtain private backend code without permission would be unauthorized and potentially illegal.
A public code repository might contain it, but developers generally won’t provide private server code just because the site is publicly accessible.

Thanks, that clears up the difference between the frontend and backend.
