Notes:

   1.

      The " entity was mistakenly omitted from the HTML 3.2 specification. While use of " generates error reports when validating against 3.2, browsers have continued to recognize the entity and its use is generally safe (sticklers may wish to use " instead). The omission has been corrected in the HTML 4.0 specification.
   2.

      The non-breaking space (  or  ) can be used not only to prevent the separation of words by line wraps, but also to force a space equal in size to a keyboard/spacebar space (useful for indentation or wider word separation) or to "hold" space in the empty cell of a table (as in the table above).
   3.

      The middle dot (· or ·) can be used as a bullet and embedded anywhere in text. Because it is equal in size to a period, however, it may be necessary to apply <B> </B> or tags to enhance its graphic effect (use of <FONT SIZE="x"> </FONT> or <BIG> </BIG> elements is not recommended, as these will alter the character's vertical spacing relative to other characters in the same line).
