I have a text splitted in 4 columns and it works perfectly in Safari I don\'t know why I can see just 2 columns in Google Chrome.
Tested with Chrome 55.0.2883.95 (64
After suffering this issue with Chrome 80.0 the solution was from a comment on the question:
.childbrick {
break-inside: avoid-column;
}
This fixed both the odd lack of columns in Chrome as well as the column splitting which occurred if not using display:inline-block; .
The comment references a Firefox issue with this workaround but I have found no such issues with Firefox version 73.
