Spaces and Tabs

There are a handful of codes for spaces, tabs, and line breaks:

Most of the time, these are absolutely useless, as web browsers ignore (and close up) any "white space" in source code when rendering pages for display.

The space character is sometimes (mis)used to create a non-breaking space between two words (though the <NOBR> tag is a better choice) or to force the display of multiple spaces in sequence (when the coder is either lazy or doesn't know how to properly format output).

Neither are they particularly useful for parsing code others have written, unless the person who wrote the code decided to use them for some reason. And yes, I wouldn't have bothered to say that if I hadn't had to deal with it a couple of times.
