VSCODE - Toggle in and out

My current layout in VSCODE is three columns. My first column is html, 2nd is css and third is my preview screen of whats happening live.

I’m trying to figure out how to make my 3rd column (preview) as fullscreen so I can quickly see how my website looks realy quick. A plus, if I can make a hotkey to do the toggling as well.

FYI, I’m fairly new to VSCODE and getting used to it.

Go into your Keyboard Shortcut setting and search for toggleEditorWidths and set a key bind. I assume it works for the preview as well but I’m not sure how you are previewing.
