I have a picture in float:right at bottom of page but caption goes to top of next column.
How do I avoid this?

I would like to use
.Picture_Group {break-inside: avoid)


.Picture_Group {
height: 1in ;
float: right ;
margin: 0 ;
padding: 1pt;
text-indent: 0pt;
}

.Picture_Caption {
display: block ;
text-align: center;
margin: -6pt 0 0 0 ;
padding: 0 0 0 0 ;
font-size: 70% ;
font-weight: bold ;
}

How about using the column-break-inside property?
