Many web pages use font sizes that are very small, and when jsMath is incorporated into these pages, superscripts and subscripts may become unreadable because they are so small. In these cases, you may wish to use the
smallFontsplugin, which changes the sizes used for the fonts in super- and sub-scripts to make them more readable.
You do this by including<SCRIPT SRC="path-to-jsMath/plugins/smallFonts.js"></SCRIPT>just before the command that loads
easy/load.js, and after setting any values for the
jsMathvariable, if any. This will make the results match the TeX output slightly less closely, but can improve the results for your readers. Note that if
smallFontsis used when the page fonts are sufficiently large already, then the sub- and super-scripts will look unusually large, so you should only use this plugin when the page actually uses small text fonts.
You may also wish to set the jsMath scaling factor to enlarge the math in relation to the surrounding text, as that will help make the smaller fonts more readable as well. See the documentation on changing the font size.
