Separators:
Curabitur a velum purus. Nam vel risus a elit malesuada dictum. Quisque rutrum neque nec tortor mollis ut vulputate lectus rutrum. Suspendisse non quam enim. Nam elit orci, vestibulum et mattis ullamcorper, venenatis a urna. Donec vel ullamcorper dui. Fusce lacinia sagittis sem, ac viverra risus molestie non. Cras fringilla ultricies feugiat. Donec in velit ligula. Curabitur orci nunc, dictum ac consequat nec, ornare et sem. Morbi hendrerit aliquam tortor, sed convallis sapien bibendum sed.
This is example of separator - the line below is called by <div class="hr"></div> - it expands automaticly to fit into available space.
Separator can have the themes typical dash as well: <div class="hr"><div class="thedash"></div></div>
You can use simple <hr /> as well.
There is also a clearfix class available, that forces new row for grids (it's invisible): <div class="clearfix"></div>
