This is a paragraph of text that's double-spaced. This means
that the leading, or interline spacing, is different
from standard text layout on a Web page. Within this
paragraph, I can also have
some words that are widely spaced due to
the word-spacing value and, of course,
some words that are narrowly spaced,
too.
By comparison, this paragraph doesn't have any special line-height
specified, so it's "single spaced." Notice the difference in the
space between lines of text.
