Is it safe to override .phx-connected in app.css?

I was goofing around with a Tailwind template with LiveView, but the template wouldn’t expand to full width. I made sure I deleted all of the containers generated by Phoenix and that the viewport was specified, but it still didn’t work.

It boiled down to the .phx-connected class limiting the width of the live view content. Setting its width to 100% solved the problem, but is this the correct way to solve this issue? Just want to make sure it doesn’t have any unintended consequences.
