* smallFonts.js
|
|
*
|
|
* Part of the jsMath package for mathematics on the web.
|
|
*
|
|
* This file changes the sizes of fonts used in subscripts so that they
|
|
* are larger. This can be helpful if jsMath is used on a page with a
|
|
* small font size, where the subscripts may tend to disappear.
|
|
* It should be loaded BEFORE jsMath.js.
