Version 3 is now the current version of MathJax. This document is for version 1.

The MathZoom extension

The options below control the operation of the Math-Zoom feature that allows users to see an enlarged version of the mathematics when they click or hover over typeset mathematics. They are listed with their default values. To set any of these options, include a MathZoom section in your MathJax.Hub.Config() call. For example

  MathZoom: {
    delay: 600

would set the delay option to 600 milliseconds.

Mathematics is zoomed when the user “triggers” the zoom by an action, either clicking on the mathematics, double-clicking on it, or holding the mouse still over it (i.e., “hovering”). Which trigger is used is set by the user via the math contextual menu (or by the author using the menuSettings configuration section).

delay: 400

This the time (in milliseconds) that the mouse must be still over a typeset mathematical formula before the zoomed version is displayed (when the zoom trigger is set to Hover).

styles: {}

This is a list of CSS declarations for styling the zoomed mathematics. See the definitions in extensions/MathZoom.js for details of what are defined by default. See CSS Style Objects for details on how to specify CSS style in a JavaScript object.
