Use {{-}} after any floating elements and before elements you do not wish to float together with the first set.
Example:
This is +----------------+
text. | |
| |
I want | Floating image |
this text | |
go below | |
the image. +----------------+
If you use this template between the two paragraphs, the example will look like this:
This is +----------------+
text. | |
| |
| Floating image |
| |
| |
+----------------+
I want this text go below the image.
The unusual name of this template is a mnemonic for an imaginary horizontal line, which separates floating elements above from those below.
