That’s it. Not as complex as I seemed to recall, though it was maybe a more complex example page I was looking at.
I suppose you would make a .sandbag
class like that to apply to any element you want to sink a float in.
.sandbag:before {
content:"";
float:right;
height:50px;
outline:1px solid magenta; /* TEST Outline. To Be Deleted */
}
<div class="contentBlock sandbag">
<div class="right">
