It most definitely is not. The problem with CSS is precisely that it was invented by engineers who did not understand hundred years old printing / typesetting concepts.
And somehow the text jumps around when you move the pic and other random shit can happen. I've used Word and Writer I think for 15 years and images and text documents are just a janky experience in both. Especially when there's loads of pics.
I wish that solved, believe me. But it hasn't stopped the text jumping and paging weird when moving pictures. It shouldn't do that but text documents with pictures are just wonky.
