Microsoft doesn't consider IE a browser anymore, they call it a "compatibility solution"[0][1]. If a site looks bad in IE, I think that is ok these days. (functional but ugly, is there an industry phrase to encapsulate this idea?) IE 11 was released 5 year ago...

Graceful degradation.

Thank you. I guess I always considered that a phrase regarding features where a browser doesn't have a feature yet, but will in the future. But I guess it works well for the other direction as well.

(ie, a browser that will never have any new features)

That's progressive enhancement.

Progressive Enhancement: Starting from some baseline, ideally static content, and building in features that newer, usually visual browsers can support

Graceful degradation: What happens if things don't work perfectly, or some browser doesn't support a feature, or network connectivity is shit so your js file doesn't load.

Flexbox: "Partial support is due to large number of bugs present"

Grid: "Partial support in IE refers to supporting an older version of the specification"

https://caniuse.com/#search=grid

IIRC IE implemented Grid first but their spec had enough problems that the standard isn't much like it.

It's iffy, but IE was the first to support any grid spec. I'd build a float based layout and progressively enhance newer layout methods

Im not a UI dev but for my basic stuff I stuck with bootstrap since it supports every browser for positioning.

bootstrap 5 is dropping IE support: https://github.com/twbs/bootstrap/pull/23586

I use Suzy grids 2 for ie and everything above and it works great.
