Controlling line breaks

If you've ever used <br>'s to force blocks of text to wrap 'perfectly', you'll probably know that this screws up in fluid layouts:

So the other day I was wondering:

If you apply display: none to a <br>, does it remove the line break?

Yeah it does!

Combining this with Media Queries, it's possible to remove all the <br>'s before the text starts to wrap. Best of both worlds! :)
