CSSFONT STACKS

What are fontstacks?

Font stacks are about creating arelevant and comprehensive

list of fall-back fonts - based onaspect ratio, platforms, operating

systems etc.

A bad example

body{

font-family: Verdana, Arial,sans-serif;

}

What’s wrong here?

Problem 1:There are a limited number of

fallback fonts.

Problem 2:The fonts used may not be

available for all operating systems(eg. Windows, Mac, Linux).

Problem 3:The fonts used have different

“aspect ratios”

What isaspect ratio?

Some fonts, especially thosespecifically designed for screen,may appear wider and/or taller

than other fonts.

ax axVerdana @200pt Helvetica @200pt

This means that these fonts havea larger aspect ratio.

If you use font’s with differentaspect ratio, some people maysee your pages with a much

smaller font size than others.

body{

font-family: Verdana, Arial,sans-serif;

}

Larger aspect ratio

Smaller aspect ratio

Ideally, your font stacks shouldinclude a range of fonts that have

a similar aspect ratio.

The basic fontstacks based on

aspect ratio
