[LON-CAPA-users] Increasing the math font in the XML style sheet

[Seema Ali]

I'm using jsMath.  I really like it except the expressions/numbers in the fractions are too small.  Is there a way to modify the math class and increase the font size to +1 or +2 of whatever font the user is using?

I tried to define m and /m in the xml style sheet to increase the font size but that didn't work, it ended up not processing the math environment stuff and printed it out on the web.

Hi,

You might want to try the other math display modes, for example MimeTeX or jsMath. You can set those in your course preferences.

Main Menu -> Modify Course Configuration -> Display of Resources -> Force use of a specific math rendering engine

Needs course reinitialization to kick in.
