In boostrap 4, "well" is replaced by "card".
However, I don't get the same result here :
<ul class="list-unstyled">
<li class="card">...</li>
<li class="card">...</li>
</ul>
Here I just replaced "well" with "card". Obviously it seems we don't use card this way. But I cannot find how to get the same result reading the docs.
With bootstrap 3 and "well", we had a nice box with a grey backgroud, for each list item. And every list item was wrapped in default padding/margins.
What is the boostrap 4 equivalent ?
