HTML and CSS Reference
Now let's add a font-size-adjust property:
font-family: "Yanone Kaffeesatz", sans-serif;
Again, everything is fine if the
font is available.
But this time, if the font isn't
available, the fallback font takes
up a similar height.
Note that font-size-adjust only impacts the x-height—the width is still
different. The property's main advantage is that it preserves the verti-
cal rhythm of your blocks of text.
Advanced font control
This section looks at some of the
advanced features offered by mod-
ern fonts and how they can be con-
trolled from CSS . We'll start with
ligatures : the replacement of
sequences of separate characters
with a single, joined glyph (the typo-
graphical term for the elements of a
font) and then explore some fea-
tures available for numbers before
finishing with fancy text options
known as contextual swashes .
All of these features are attributes of the font being used.
CSS doesn't create additional glyphs—they have to be present
in the font—but it lets you control when they're used.
