Allow resizing board

Using a 14.1" widescreen monitor with broswer display at 100% and pretty much the maximum possible screen area given to websites (no browser menu, small icons in windows taskbar; but with the latter "locked", and not in full-screen mode), the board and graph cannot be viewed together at they don't fit the display area.

When checking an analysed game, that's mostly what I use, and with arrow keys. So the situation necessitates using the mouse as well, or instead (not convenient to my kind of user).

Not a disaster - I know - but it would be great if the board could be resized. It would also allow people to play on a larger area, and such benefits.

Maybe fit the board in a textarea like the one I'm typing into here?

Can messing up the rest of the layout be avoided easily?

I'd love to be able to resize the board separately. It's often too large for me. I'd like a small board upon occasion, especially when I'm pondering a correspondence position in a background window

Also, remember size (and position? Possibly getting ahead of myself with optimism) for next session.

As mentioned in
lichess.org/forum/lichess-feedback/board-size-setting#4
the board is actually resizable, but the problem reported here was with it minimised.

Any dev care to comment on the feasibility of using a textarea for the board?

You could zoom out with Ctrl - (Ctrl + to zoom in, Ctrl 0 to reset to default).
Alternatively, you could try Stylus with userstyles, e.g.

.lichess_game .cg-board-wrap { width:416px !important; height:416px !important; }
.underboard .center { width:416px !important; }
div.lichess_game { height:416px !important; }

I haven't tested this though...

Thank you, bufferunderrun.

1. Zooming will affect the entire display.

2. Sorry, not familiar with this extension. Will it allow dynamic resizing, as in dragging a window's corner? If it requires manual editing it's probably too cumbersome.

No, it will just allow you to use userstyles, so you can change how things look like on the site using CSS.
