Documentation
&#123;&#123;-&#125;&#125; contains the markup:

This causes any previously-established float to clear.

The unusual name of this template is a mnemonic for an imaginary horizontal line, which separates floating elements above from those below. Some editors prefer the mnemonic clr ("clear"), which simply redirects here.

Usage
Use this template after any floating elements and before elements you do not wish to float together with the first set.
