Header. Font Size and Line Height

Hello,

I created the following header:
http://www.27lamps.com/Beta/Typography/Typography.html

Where Font Size is the same as Line Height: 2.0em.

Shouldn't the border be next to the text?

Thanks,
Miguel

No, both are declared using the same expression, but it has different
meanings.

For font-size, the em unit means the size of the font of the parent element.
Even if you set line-height to 1em, making it equal the font size, the
border does not normally touch letters. Remember that the font size is the
total height of the font, normally encompassing ascenders, descenders, and
diacritic marks. A letter like "H" should be expected to have a height that
is notably less than the font size.

Actually if the text contains letters like "j" and "Å", those letters might
extend to the border (set for an element with line-height: 1em) and even a
little beyond. But most letters - for the Latin script at least - have
spacing below and above them.

Pardon? You quoted my entire message, so it is impossible to see how your

And taken in isolation, your question looks rather trivial. Spacing can be
achieved using margins or padding or both. What's so special here that you
need to ask?

Of course line-height can _also_ be used for spacing. What made you think it
could not? But it's not wise to use it for anything that can be achieved
using margin or padding, since line-height affects... well, line height,
i.e. _line_ spacing. This is quite important when the text may get divided
into two or more lines, as it usually can (there is no lower limit to window
width that people may use).

But usually margins are a good choice because they collapse-- for
example bottom margin of H1 collapsing with top margin of the P that
follows it.

I will use margin ... the borders where just a visualization helper.
