No, this is terrible CSS. grid handles this perfectly.

I have a hard time differentiating when I should use grid and when I should use flex-box. In this case, setting up a grid seems like overkill.

Seems more like a browser default issue than a tool choice issue.

If you need flexing, use flex box.

You probably don't need flexing.

/If you don't know what flexing is/, you should use grid.
