For a Bootstrap 4 card deck with fixed-widthcards, do this:
对于带有固定宽度卡片的 Bootstrap 4 卡片组，请执行以下操作：
Put each card into a column with the classes col-auto mb-3(auto-width column + margin-bottom with three units).
将每张卡片放入带有类别的列中col-auto mb-3（自动宽度列 + 带三个单位的边距底部）。
To center them, add the justify-content-centerclass to the row.
要将它们居中，请将justify-content-center类添加到行中。

Deck makes cards equal height.
甲板使卡片的高度相等。
Adding a row-deleting deck was correct. Adding col-lg-3 col-md-2 col-sm-12 will give a four-cards desktop, etc. down to one on a phone.
添加行删除牌组是正确的。添加 col-lg-3 col-md-2 col-sm-12 将使四卡桌面等降为手机上的一张。
Set the height using the height of the largest number so an "OK" looks straight.
使用最大数字的高度设置高度，以便“OK”看起来是直的。
