The sequence can be interpreted in at least two different ways, depending on the DOCTYPE of the document. For HTML 4.01 Strict, the ‘/’ terminates the tag ‘). However, since many browsers don’t interpret it this way, even in the presence of an HTML 4.01 Strict DOCTYPE, it is best to avoid it completely in pure HTML documents and reserve its use solely for those written in XHTML.
