Problems with interface

My text editor is weird, it is not like the old one, looks incomplete and confuse

I love thissite so much, i really would like someone to help me.
Thanks fo the atention.

FCC changed the in-browser editor it is using. Just use it the same way you used the old one.

But it is not just the editor, the phone at right side disapeared and some changes in CSS are not working like board

The preview pane doesn’t look like a phone anymore. That’s a design decision that the team made. It is, however, working.

Ok, but there is a way to use the old one?
