The slash (which goes on the right) may be a closing tag, but it is also self closing, meaning that you don't need the opening tag for it to work. It works very well for line breaks. By the way, there are some interfaces that only accept the one with the slash. (Also, that line break above was done with the < b r / > tag. Without any spaces, obviously).
