.card-block missing clearfix

[aimeos]

.card components that contain floats (e.g. "col-sm-6" grids) have no height because of the floating elements. Can be fixed by adding:

.card-block:after {
    display: block;
    clear: both;
    content: "";
}

Erm, you're referring to clearfix, right?

[aimeos]

Not the .clearfix class itself. Divs with .card-block have simply no height if they contain only floating elements like grids.

Not the .clearfix class itself.

I was referring to the abstract concept of clearfix. Bootstrap implements it both as a mixin and as a class though.

Divs with .card-block have simply no height if they contain only floating elements like grids.

Yes, that's what clearfix fixes. So the obvious (and seemingly reasonable) solution here would be to make .card-block include the clearfix mixin.

Yes, sure.
