I wouldn't use
unless you intend to put content within it. Of course, this is merely an opinion (as I assume most answers will be).
However, it may be easier to style a
tag (there are more options at least) which may lend itself to be used more often. My only problem is that this is not very easy to read (when reading code) and I feel like those styles could be applied elsewhere (possibly to the tags that would surround the
tag.
Also, as other have stated, a
tag should be used to separate content within a block element (such as the
tag). If you are using the following:
some content...
some other content...
Then I would argue that you should use styles on one or both of the tags surrounding the p.break
tag to do any spacing that is required.
